src/app-secrets.js (1)

32-32: Remove unnecessary return statement.

The return null; statement after sending the error response is unnecessary. The function execution will naturally end after sending the response.

Apply this diff to remove the unnecessary return:

-      return null;

src/util/middlewares.js (2)

22-24: Approve changes with a minor suggestion.

The renaming from validateUserMiddleware to validateSessionMiddleware and the corresponding logic updates are consistent and improve the clarity of the session-based validation approach.

Consider adding a type annotation for the session variable to improve code readability:

-let session = await validateSession(req, res);
+let session: SessionType = await validateSession(req, res);

Replace SessionType with the appropriate type definition for your session object.

28-28: Consider future improvements for session management.

Acknowledging the previous discussion about express-session, the current implementation is a reasonable solution for the immediate needs. However, as the application grows, consider the following improvements:

1. Implement a custom session store to persist sessions across server restarts.
2. Add session expiration and renewal logic.
3. Implement CSRF protection for session security.

These enhancements can be made incrementally without immediately adopting express-session.

src/db.js (1)

65-65: Add a comment explaining the CHUNK_SIZE constant.

The CHUNK_SIZE of 999 is used to avoid SQL query limits, but this might not be immediately clear to other developers. Consider adding a comment to explain the reasoning behind this specific value.

Here's a suggested improvement:

-  const CHUNK_SIZE = 999;
+  // Use 999 as CHUNK_SIZE to stay below the common SQL limit of 1000 placeholders per query
+  const CHUNK_SIZE = 999;

src/app.js (1)

Line range hint 1-97: Overall assessment: Enhancements for authentication and user management.

The changes in this file successfully introduce new functionality for admin and OpenID routes, along with improved authentication checks. The additions are consistent with the existing code structure and follow good practices. The toggleAuthentication check adds an important safeguard to ensure proper authentication configuration before the server starts.

Consider addressing the minor suggestions from previous reviews, such as using process.exit(-1) and removing the unnecessary exit import.

src/app-gocardless/app-gocardless.js (1)

Line range hint 1-262: Coordinate with related PR and update documentation.

Given that this PR is meant to work in conjunction with PR #2945, it's important to ensure that the changes in both PRs are compatible and complementary.

Consider the following recommendations:

1. Cross-reference the changes in PR #2945 to ensure they align with the middleware update in this file.

2. Update any relevant documentation, including:

   • API documentation to reflect the new session-based authentication
   • Developer guides or READMEs that explain the authentication flow
   • Any configuration files that might need adjustments for the new middleware

3. If not already done, consider adding comments in the code to explain the rationale behind the middleware change and any specific behaviors developers should be aware of.

4. Evaluate if this change necessitates updates to client-side code or SDKs that interact with these routes.

These steps will help maintain consistency across the project and ensure that all team members understand the implications of this authentication change.

src/app-admin.js (1)

1-322: Summary of review for src/app-admin.js

Overall, this file provides a comprehensive set of endpoints for user and file management with good attention to security through session validation and permission checks. However, there are several areas for improvement:

1. Asynchronous operations: Ensure proper handling of asynchronous functions, especially for isAdmin checks.
2. Error handling: Implement more robust error handling, particularly for database operations.
3. Performance: Consider optimizing bulk operations, such as user deletion.
4. Security: Review the exposure of configuration data and implement stricter input validation.
5. Code structure: Consider breaking down larger route handlers into smaller, more manageable functions.
6. Consistency: Ensure consistent use of async/await throughout the file.

Addressing these points will significantly improve the robustness, security, and maintainability of the application.

src/app-sync.js (1)

Line range hint 1-424: Overall improvements in security and access control.

The changes in this file significantly enhance security, access control, and user management. Key improvements include:

1. Better session validation
2. Admin-specific functionality
3. Improved file ownership tracking
4. More granular access control in file listing

These modifications effectively address the previous concerns about permission checks.

Consider adding more robust error handling for the new logic, especially in the /list-user-files endpoint. For example:

app.get('/list-user-files', (req, res) => {
  try {
    const canSeeAll = isAdmin(req.userSession.user_id);
    // ... existing logic ...
  } catch (error) {
    console.error('Error in list-user-files:', error);
    res.status(500).send({ status: 'error', message: 'Internal server error' });
  }
});

This will ensure that any unexpected errors are caught and handled gracefully.

src/app-openid.js (1)

60-60: Typo in error message reason: 'already-bootstraped'

There's a typo in the error message on line 60: 'already-bootstraped' should be corrected to 'already-bootstrapped'.

src/account-db.js (1)

216-219: Simplify variable naming for clarity

The variable enabledMethodsButOpenId could be renamed for better readability. Consider using a name like nonOpenIdMethodsEnabled or enabledNonOpenIdMethodsCount to more clearly convey its purpose.

src/app-secrets.js (4)

26-30: Approve error response structure.

The error response structure looks good and follows the suggested format from a previous review. It provides clear information about the reason for the error, which is helpful for debugging and user feedback.

---

17-18: ⚠️ Potential issue

Fix asynchronous database query.

The database query is not properly awaited, which could lead to unexpected behavior. This issue was previously identified in a past review.

Apply this diff to fix the issue:

-  const { method } =
-    getAccountDb().first('SELECT method FROM auth WHERE active = 1') || {};
+  const { method } =
+    (await getAccountDb().first('SELECT method FROM auth WHERE active = 1')) || {};

22-34: ⚠️ Potential issue

Fix asynchronous admin check and approve error response structure.

The admin check is not properly awaited, which could lead to unexpected behavior if isAdmin is an asynchronous function. This issue was previously identified in a past review. The error response structure looks good and follows the suggested format.

Apply this diff to fix the asynchronous issue:

-    let canSaveSecrets = isAdmin(req.userSession.user_id);
+    let canSaveSecrets = await isAdmin(req.userSession.user_id);

---

3-3: Approve changes to imports and middleware.

The new imports and middleware change appear to be in line with the PR objectives. However, it's important to ensure that these changes are consistent across the codebase.

Let's verify the usage of these new imports and the middleware change:

Also applies to: 6-6

src/util/middlewares.js (1)

46-46: Export statement correctly updated.

The export statement has been properly updated to reflect the renaming of validateUserMiddleware to validateSessionMiddleware.

jest.global-setup.js (2)

15-20: Implement suggested improvements from previous review.

The setSessionUser function could benefit from the improvements suggested in the previous review:

1. Make the token a parameter for increased flexibility.
2. Add error handling and return the result for better feedback.

Here's the suggested implementation:

const setSessionUser = (userId, token = 'valid-token') => {
  return getAccountDb().mutate('UPDATE sessions SET user_id = ? WHERE token = ?', [
    userId,
    token,
  ]).then(result => {
    if (result.changes === 0) {
      throw new Error('No session updated. Token might be invalid.');
    }
    return result;
  });
};

These changes will make the function more flexible, provide better error handling, and give feedback on the operation's success.

---

34-44: Ensure consistent session setup.

The session management logic looks good overall. Deleting all sessions and creating new ones ensures a clean state for tests. However, there's still an inconsistency in the session setup:

1. Two session records are created, one for 'valid-token' and another for 'valid-token-admin'.
2. setSessionUser is called only for 'valid-token', but not for 'valid-token-admin'.

To address this, consider one of the following options:

1. If setSessionUser is necessary, call it for both tokens:

   setSessionUser('genericAdmin', 'valid-token');
   setSessionUser('genericAdmin', 'valid-token-admin');

2. If setSessionUser is redundant (since the sessions are already created with user IDs), you might want to remove the setSessionUser call entirely.

Choose the option that best fits your testing requirements and ensures consistency across all session setups.

src/util/validate-user.js (4)

4-4: LGTM: Import statement reordering.

The repositioning of the getSession import statement is acceptable and doesn't affect the functionality.

---

6-6: LGTM: New constant for token expiration.

The introduction of TOKEN_EXPIRATION_NEVER is a good practice. It provides a clear, semantic constant for representing tokens that never expire, improving code readability and maintainability.

---

31-42: LGTM: Token expiration check enhances security.

The new token expiration check is a valuable addition that improves the application's security. It correctly uses the TOKEN_EXPIRATION_NEVER constant and provides an appropriate error response.

The use of a 401 status code for expired tokens aligns with HTTP standards and addresses the previous review comments. Well implemented!

---

12-12: LGTM: Function rename improves clarity.

The renaming of validateUser to validateSession better reflects the function's purpose. This change enhances code readability and maintainability.

Please ensure that all references to this function have been updated across the codebase. Run the following script to verify:

src/db.js (1)

53-77: LGTM! Well-implemented deleteByIds method.

The new deleteByIds method is a solid implementation for bulk deletion of records. It handles large arrays of IDs efficiently by using a chunking approach, and it properly accumulates and returns the total number of deleted rows.

src/app.js (4)

14-15: LGTM: New imports for admin and OpenID functionality.

The addition of adminApp and openidApp imports aligns with the PR objectives and follows the existing import pattern in the file.

---

16-16: LGTM: Import of toggleAuthentication function.

The import of toggleAuthentication from './account-db.js' is correct and aligns with its usage later in the file.

---

55-56: LGTM: New route handlers for admin and OpenID.

The addition of middleware for '/admin' and '/openid' routes is consistent with the existing pattern and aligns with the PR objectives for enhancing authentication and user management.

---

94-94: LGTM: Usage of toggleAuthentication for critical error handling.

The addition of the toggleAuthentication check in the run function is a good practice for ensuring the application only starts if authentication is properly configured.

As a reminder, consider using process.exit(-1) instead of exit(-1) as suggested in a previous review comment.

src/app-gocardless/app-gocardless.js (2)

Line range hint 1-262: Ensure comprehensive testing of all routes with the new middleware.

While the middleware change is the only modification in this file, it's crucial to verify that all existing routes continue to function correctly with the new validateSessionMiddleware. The shift from user-based to session-based validation could potentially affect the behavior of some routes.

To ensure the integrity of the application, please conduct thorough testing:

1. Test all existing routes (/link, /status, /create-web-token, /get-accounts, /get-banks, /remove-account, /transactions) with various scenarios, including:

   • Valid sessions
   • Invalid or expired sessions
   • Different user roles or permissions (if applicable)

2. Pay special attention to error handling, especially in the /transactions route, to ensure that the new middleware doesn't interfere with the existing error categorization and responses.

3. Verify that the goCardlessService methods are still receiving the necessary user information from the new session-based middleware.

Consider adding or updating integration tests to cover these scenarios systematically.

---

17-17: Middleware update looks good, but verify compatibility.

The change from validateUserMiddleware to validateSessionMiddleware aligns with the PR objectives related to OpenID integration. This update suggests a shift towards session-based authentication, which is a common approach in OpenID implementations.

31-108: Review User and Session Management for Multi-User Support

The current implementation appears to primarily handle a single user with an empty user_name. In a multi-user environment, this could lead to issues with user identification and session management.

Consider modifying the authentication flow to support multiple users:

• Accept a username parameter in addition to the password.
• Update database queries to use the provided username.
• Ensure that sessions are correctly associated with the authenticated user.

To verify if multi-user support is needed, you can run the following script:

This script helps identify if multi-user functionality is present or needs to be implemented.

✅ Verification successful

Multi-User Support is Properly Implemented

After reviewing the codebase, it is clear that multi-user functionality is supported. The use of an empty user_name in password.js serves as a bootstrap mechanism for the initial admin user. Subsequent users are managed with proper user_name fields, ensuring correct user identification and session handling.

Line range hint 1-448: Summary of changes and recommendations for further improvements

The changes in this file have significantly enhanced security, access control, and file ownership tracking. Key improvements include:

1. Transition to session-based validation
2. Implementation of role-based access control for file listing
3. Enhanced file ownership tracking in the upload process

While these changes are positive, there are areas for further improvement:

1. Implement comprehensive permission checks across all endpoints, preferably using middleware for consistency.
2. Optimize database queries, particularly in the /list-user-files endpoint, by adding appropriate indexes.
3. Ensure proper error handling and input validation across all endpoints.

Consider the following architectural improvements:

1. Separate route handlers into individual files or modules for better organization and maintainability.
2. Implement a centralized error handling mechanism.
3. Use dependency injection for database access to improve testability.

To facilitate these improvements, it would be beneficial to conduct a comprehensive security audit and performance profiling of the application.

183-185: Avoid throwing generic errors without context

In the deleteUserAccessByFileId method, the error thrown when userIds is invalid provides limited information. Including more context in the error message can aid in debugging and improve developer experience.

Consider updating the error message to include the invalid userIds value:

       if (!Array.isArray(userIds) || userIds.length === 0) {
-        throw new Error('The provided userIds must be a non-empty array.');

15-15: ⚠️ Potential issue

Partial implementation of permission checks, further improvements needed.

While some endpoints (like /list-user-files) now implement role-based access control, the concern raised in the previous comment about applying permission checks to most endpoints remains partially unaddressed.

Consider implementing a middleware solution for bulk application of permission checks to relevant endpoints. This would enhance security and ensure consistent access control across the application.

Example middleware implementation:

function permissionCheckMiddleware(req, res, next) {
  // Check if the user has permission to access the requested resource
  // This could involve checking the user's role, the resource they're trying to access, etc.
  if (userHasPermission(req.userSession, req.path)) {
    next();
  } else {
    res.status(403).send({ status: 'error', reason: 'permission-denied' });
  }
}

// Apply the middleware to all routes that need permission checks
app.use('/protected-routes', permissionCheckMiddleware);

To assess the current state of permission checks, run the following:

#!/bin/bash
# Description: Analyze current permission check implementation

echo "Checking for existing permission checks:"
rg "isAdmin|userHasPermission|req\.userSession" src/app-sync.js

echo "Listing all route handlers:"
rg "app\.(get|post|put|delete|patch)" src/app-sync.js

Compare the output to identify routes that might need additional permission checks.

Line range hint 338-384: Improved access control and file listing functionality.

The changes in the /list-user-files endpoint significantly enhance access control and file listing functionality:

1. Implemented role-based access control, allowing admins to see all files while regular users see only their own and shared files.
2. Added a query to fetch comprehensive user access information.
3. Enhanced the response to include owner and access information.

These improvements provide better security and more detailed file access information to the client.

jest.global-setup.js (2)

7-25: LGTM! Consider returning the created user ID.

The createUser function is well-structured with good error handling and input validation. However, it could be improved by returning the created user ID or a success indicator. This would allow callers to confirm the operation's success programmatically.

Consider modifying the function to return the user ID:

const createUser = (userId, userName, role, owner = 0, enabled = 1) => {
  // ... existing code ...

  try {
    // ... existing code ...
    return userId; // Return the created user ID
  } catch (error) {
    console.error('Error creating user:', error);
    throw error;
  }
};

This change would make the function more versatile without breaking existing usage.

---

37-49: LGTM! Consider using constants for token values.

The modifications to the setup function look good. Using createUser for admin creation and ensuring a clean session state are excellent practices. Creating two sessions with different tokens provides good flexibility for testing.

Consider defining constants for the token values to improve maintainability:

const VALID_TOKEN = 'valid-token';
const VALID_TOKEN_ADMIN = 'valid-token-admin';

// Then use these constants in the INSERT statements

This change would centralize these values, making them easier to update if needed in the future.

src/app.js (1)

93-93: LGTM! Authentication check added. Consider improving error handling.

The authentication check using toggleAuthentication is correctly implemented. The use of process.exit(-1) addresses a past review comment.

Consider adding an error log before exiting to provide more context:

src/app-account.js (1)

Line range hint 53-87: Improved login endpoint, but fix async handling

The login endpoint has been significantly enhanced with OpenID support and asynchronous handling. However, there's an issue in the password login case.

In the default case (password login), loginWithPassword is called without await. This could lead to unexpected behavior. Please update the code as follows:

-      tokenRes = loginWithPassword(req.body.password);
+      tokenRes = await loginWithPassword(req.body.password);

Also, make sure to apply the same fix to the 'header' case:

-          tokenRes = loginWithPassword(headerVal);
+          tokenRes = await loginWithPassword(headerVal);

src/load-config.js (2)

104-106: LGTM. Consider improving code formatting.

The implementation of the multiuser property looks good. It correctly handles various truthy values for the ACTUAL_MULTIUSER environment variable, which aligns with best practices for boolean environment variables.

Consider improving the code formatting for better readability:

  multiuser: process.env.ACTUAL_MULTIUSER
-    ? ['true', '1', 'yes', 'on'].includes(process.env.ACTUAL_MULTIUSER.toLowerCase())
-    : config.multiuser,
+    ? ['true', '1', 'yes', 'on'].includes(
+        process.env.ACTUAL_MULTIUSER.toLowerCase()
+      )
+    : config.multiuser,

This change addresses the linting error mentioned in the static analysis hints and improves code readability.

178-180: LGTM. Consider adding validation for ACTUAL_TOKEN_EXPIRATION.

The implementation of the token_expiration property looks good. It correctly uses the environment variable ACTUAL_TOKEN_EXPIRATION with a fallback to the config value.

Consider adding validation for the ACTUAL_TOKEN_EXPIRATION value to ensure it's always set to a valid option. Here's a suggested implementation:

function validateTokenExpiration(value) {
  const validOptions = ['never', '1h', '1d', '7d', '30d']; // Add all valid options
  return validOptions.includes(value) ? value : 'never';
}

// In finalConfig
token_expiration: validateTokenExpiration(
  process.env.ACTUAL_TOKEN_EXPIRATION || config.token_expiration
),

This change ensures that token_expiration always has a valid value, preventing potential issues in the application due to invalid configuration.

1-132: 🛠️ Refactor suggestion

Address overarching concerns in password management implementation

While the individual functions have been reviewed, there are some file-wide concerns that should be addressed:

1. Consistent error handling:

   Consider implementing a consistent error handling mechanism across all functions. This could involve creating custom error types or using a standardized error object structure.

2. SQL injection prevention:

   Ensure that all user inputs are properly sanitized before being used in SQL queries. While the current implementation uses parameterized queries, which is good, it's crucial to verify that this practice is consistently applied throughout the file and in any future modifications.

3. Security logging:

   Implement logging for security-sensitive operations such as password changes, failed login attempts, and user creation. This will aid in auditing and debugging. Consider using a logging library that supports different log levels.

4. Password policy enforcement:

   The current isValidPassword function only checks if the password is not null or empty. Consider implementing a more robust password policy (e.g., minimum length, required character types) to enhance security.

5. Rate limiting:

   Consider implementing rate limiting for sensitive operations like login attempts to prevent brute-force attacks. This might involve tracking failed attempts and implementing temporary lockouts.

Addressing these concerns will significantly enhance the overall security and robustness of the password management system.

✅ Verification successful

SQL query parameter usage verified

All SQL queries in src/accounts/password.js utilize parameterized queries consistently, effectively mitigating SQL injection risks.

2. How is the 'never' value interpreted in the application?
3. Are there any security implications of setting this to 'never' by default?

---

189-189: LGTM. Good addition to debug logging.

The new debug log for the login method is a helpful addition. It provides valuable information during configuration debugging and uses the nullish coalescing operator appropriately to fall back to 'password' if loginMethod is not set.

-function hashPassword(password) {
-  return bcrypt.hashSync(password, 12);
+async function hashPassword(password) {
+  return await bcrypt.hash(password, 12);

src/accounts/openid.js (1)

1-256: Overall assessment: Functional but needs improvements

The OpenID implementation is functional and covers the necessary steps for authentication. However, there are several areas that could be improved:

1. Error handling should be more consistent and informative throughout the file.
2. Some functions, particularly loginWithOpenIdFinalize, are complex and could be refactored into smaller, more manageable functions.
3. Security measures, such as token validation and protection against potential abuse, should be enhanced.
4. Code documentation could be improved, especially for complex processes like PKCE.
5. Consider making some hardcoded values (like expiration times) configurable.

These improvements would enhance the maintainability, security, and robustness of the OpenID implementation.

Consider implementing the following architectural improvements:

• Add a configuration management system to handle OpenID settings without manual database edits.
• Implement a more robust error handling and logging system.
• Add rate limiting and additional security measures to prevent potential abuse of the authentication process.
• Create a separate module for user management operations to improve separation of concerns.

src/app-sync.js (1)

Line range hint 1-438: Summary: Improved multi-user support with suggestions for further enhancements

The changes in this file significantly improve multi-user support and access control:

1. Introduction of validateSessionMiddleware for base authentication.
2. Enhanced file ownership tracking in the upload endpoint.
3. Improved access control in the list-user-files endpoint, differentiating between admin and regular users.
4. More detailed file information including owner and access details in responses.

These changes align well with the PR objectives. However, there are opportunities for further improvements:

1. Implement granular permission checks for specific endpoints (e.g., /sync, /upload-user-file) to ensure users can only access resources they have permissions for.
2. Review and update error handling to provide more specific error messages related to permissions and access control.
3. Consider implementing audit logging for sensitive operations to track user actions.

For future iterations, consider implementing a comprehensive role-based access control (RBAC) system to manage permissions more flexibly and securely.

Improve changePassword function for better performance and clarity

The changePassword function can be improved in terms of performance and clarity of its return value.

Consider the following changes:

1. Use asynchronous password hashing for better performance.
2. Provide a clear success indicator in the return value.

Here's a suggested refactor:

-export function changePassword(newPassword) {
+export async function changePassword(newPassword) {
   let accountDb = getAccountDb();

   if (!isValidPassword(newPassword)) {
     return { error: 'invalid-password' };
   }

-  let hashed = hashPassword(newPassword);
+  let hashed = await hashPassword(newPassword);
   accountDb.mutate("UPDATE auth SET extra_data = ? WHERE method = 'password'", [
     hashed,
   ]);
-  return {};
+  return { success: true };
 }

These changes improve performance by using asynchronous hashing and provide a clear success indicator in the return value.

1-132: Overall assessment: Solid password management implementation with room for improvement

The password.js file provides a comprehensive set of functions for password management, including validation, hashing, login, and password changes. The overall structure and logic are sound, but there are several areas where improvements can be made:

1. Asynchronous operations: Convert synchronous bcrypt operations to asynchronous for better performance and to avoid blocking the event loop.
2. Function refactoring: Break down larger functions (especially loginWithPassword) into smaller, more focused functions for improved maintainability and testability.
3. Session management: Enhance session queries to be user-specific, preventing potential conflicts in multi-user environments.
4. Error handling and return values: Improve consistency in error handling and provide clear success indicators in return values.
5. Code readability: Refactor complex logic (e.g., token expiration) for improved readability and maintainability.

Implementing these suggestions will significantly enhance the overall quality, performance, and security of the password management system.

⚠️ Potential issue

Improve session update logic and add affected rows check

The current session management logic updates the user_id for existing sessions, which might not be the intended behavior. Additionally, there's no check to ensure the update actually affected any rows.

Consider modifying the update logic as follows:

if (!sessionRow) {
  accountDb.mutate(
    'INSERT INTO sessions (token, expires_at, user_id, auth_method) VALUES (?, ?, ?, ?)',
    [token, expiration, userId, 'password'],
  );
} else {
  const result = accountDb.mutate(
    'UPDATE sessions SET expires_at = ? WHERE token = ? AND user_id = ?',
    [expiration, token, userId],
  );
  if (result.changes === 0) {
    // Handle case where update didn't affect any rows
    return { error: 'session-mismatch' };
  }
}

This change ensures that we're only updating the expiration for the correct user's session and provides error handling for mismatched sessions.

To verify the impact of this change, run the following script:

#!/bin/bash
# Check for other places where session updates occur
rg --type javascript 'UPDATE sessions'

Refactor loginWithPassword for improved maintainability and security

The loginWithPassword function is handling multiple responsibilities and has some potential issues:

1. The function is long and complex, making it hard to maintain and test.
2. Session management doesn't filter by user, which could lead to conflicts in a multi-user environment.
3. Synchronous bcrypt comparison is used, which could block the event loop.

Consider the following improvements:

1. Break the function into smaller, focused functions (e.g., validatePassword, createUserIfNotExists, manageSession, generateToken).
2. Update session queries to include user ID:

let sessionRow = accountDb.first(
  'SELECT * FROM sessions WHERE user_id = ? AND auth_method = ?',
  [userId, 'password'],
);

3. Use asynchronous bcrypt comparison:

-let confirmed = bcrypt.compareSync(password, passwordHash);
+let confirmed = await bcrypt.compare(password, passwordHash);

Remember to make the loginWithPassword function async and handle the promise appropriately.

To verify the impact of these changes, run the following script:

✅ Verification successful

Verified: loginWithPassword uses synchronous bcrypt methods

The loginWithPassword function employs bcrypt.compareSync, which blocks the event loop and may impact performance. It's recommended to replace it with the asynchronous bcrypt.compare method and refactor the function for better maintainability.

Line range hint 338-385: Approve: Improved access control and detailed file listing

The changes in the /list-user-files endpoint significantly enhance access control and provide more detailed file information:

1. Admin users can now see all files, while regular users only see their own files and shared files.
2. The response now includes owner information and a list of users with access to each file.

These improvements align well with the multi-user support objectives.

To ensure the new logic works as expected, please run the following verification:

src/load-config.js (1)

74-75: Addition of 'multiuser' and 'token_expiration' default configurations

The addition of multiuser set to false and token_expiration set to 'never' in defaultConfig is appropriate and clearly defines default behaviors.

src/services/user-service.js (1)

221-232: Consider edge cases for users without access or ownership

In the getAllUserAccess function, users who neither own the file nor have access will have haveAccess and owner set to 0. Ensure that the front-end or calling code properly handles these cases to prevent unauthorized access.

Run the following script to check if there are users without access or ownership:

Replace <FILE_ID> with an actual file ID to perform the check.

🛠️ Refactor suggestion

Refactor token expiration logic for improved readability

The current implementation of token expiration logic is correct but could be made more readable.

Consider refactoring this section as follows:

let expiration = TOKEN_EXPIRATION_NEVER;
const isValidNumberExpiration = 
  typeof finalConfig.token_expiration === 'number' && 
  finalConfig.token_expiration !== 'never' && 
  finalConfig.token_expiration !== 'openid-provider';

if (isValidNumberExpiration) {
  const currentTimestamp = Math.floor(Date.now() / 1000);
  expiration = currentTimestamp + finalConfig.token_expiration * 60;
}

This refactoring:

1. Combines the conditions for a valid number expiration.
2. Extracts the timestamp calculation for clarity.
3. Makes the logic more straightforward and easier to understand at a glance.

🛠️ Refactor suggestion

Improve error handling and add documentation

The function is well-implemented, but consider the following improvements:

1. Make error handling more consistent across the function.
2. Add comments explaining the PKCE (Proof Key for Code Exchange) process.
3. Consider making the expiry time for pending requests configurable.

Here's a suggested improvement for error handling:

  try {
    config = JSON.parse(config['extra_data']);
  } catch (err) {
-   return { error: 'openid-setup-failed: ' + err };
+   console.error('Failed to parse OpenID configuration:', err);
+   return { error: 'openid-setup-failed', details: 'Invalid configuration' };
  }

Add a comment explaining the PKCE process:

// Generate PKCE parameters
// PKCE (Proof Key for Code Exchange) is used to prevent authorization code interception attacks
const state = generators.state();
const code_verifier = generators.codeVerifier();
const code_challenge = generators.codeChallenge(code_verifier);

Consider making the expiry time for pending requests configurable:

- const expiry_time = now_time + 300 * 1000;
+ const PENDING_REQUEST_EXPIRY = 300 * 1000; // 5 minutes, make this configurable
+ const expiry_time = now_time + PENDING_REQUEST_EXPIRY;

⚠️ Potential issue

Refactor for improved readability, security, and error handling

This function is complex and handles multiple scenarios. Consider the following improvements:

1. Refactor the function into smaller, more manageable functions.
2. Improve error handling and logging.
3. Enhance security by validating the OpenID token and not exposing error details.
4. Improve the logic for determining the user's identity.

Break down the function into smaller functions, for example:

async function loginWithOpenIdFinalize(body) {
  const { code, state } = validateInput(body);
  const config = getOpenIdConfig();
  const client = await setupOpenIdClient(config);
  const pendingRequest = getPendingRequest(state);
  const grant = await exchangeCodeForGrant(client, code, pendingRequest);
  const userInfo = await getUserInfo(client, grant);
  const userId = await getOrCreateUser(userInfo);
  const token = createSessionToken(userId, grant);
  return generateRedirectUrl(pendingRequest.return_url, token);
}

Improve error handling and logging:

- console.error('OpenID grant failed:', err);
- return { error: 'openid-grant-failed: ' + err };
+ console.error('OpenID grant failed:', err);
+ return { error: 'openid-grant-failed', details: 'An error occurred during authentication' };

Enhance security by validating the OpenID token:

const tokenSet = await client.callback(client.redirect_uris[0], { code, state }, { code_verifier });
// Validate the token
if (!tokenSet.valid()) {
  throw new Error('Invalid token set');
}
const userInfo = await client.userinfo(tokenSet.access_token);

Improve the logic for determining the user's identity:

const identity = userInfo.sub || userInfo.preferred_username || userInfo.email;
if (!identity) {
  throw new Error('Unable to determine user identity from OpenID response');
}

Consider implementing rate limiting and additional security measures to prevent potential abuse of the OpenID authentication process.

🛠️ Refactor suggestion

Enhance error handling and improve configuration validation

While the overall structure is good, consider the following improvements:

1. Make error messages more specific by including the missing property name.
2. Provide more detailed error information in the catch block.
3. Consider implementing a mechanism to update OpenID configuration without manual database editing.

Here's a suggested improvement for error messages:

- if (!('issuer' in config)) {
-   return { error: 'missing-issuer' };
- }
+ if (!('issuer' in config)) {
+   return { error: 'missing-property', property: 'issuer' };
+ }

Apply similar changes for other property checks.

For the catch block:

  try {
    await setupOpenIdClient(config);
  } catch (err) {
-   return { error: 'configuration-error' };
+   return { error: 'configuration-error', details: err.message };
  }

Consider implementing an admin interface or API endpoint to update OpenID configuration without requiring manual database edits. This would improve maintainability and reduce the risk of database corruption.

🛠️ Refactor suggestion

Consider implementing granular permission checks

While the addition of validateSessionMiddleware provides a base level of authentication for all routes, the previous suggestion to implement granular permission checks for specific endpoints (e.g., /sync) is still valid. This would further enhance security by ensuring users can only access resources they have permissions for.

Consider implementing a middleware for granular permission checks. For example:

function checkPermission(requiredPermission) {
  return (req, res, next) => {
    if (hasPermission(req.userSession.user_id, requiredPermission)) {
      next();
    } else {
      res.status(403).send('Forbidden');
    }
  };
}

// Usage
app.post('/sync', checkPermission('sync'), async (req, res) => {
  // ...
});

Refactor SQL logic for clarity in getUserAccess

The current SQL query uses (files.owner = ? OR 1 = ?) to handle admin access, which can be confusing. Consider restructuring the query to conditionally include the owner check based on the isAdmin flag.

Apply this diff:

 export function getUserAccess(fileId, userId, isAdmin) {
   return getAccountDb().all(
     `SELECT users.id as userId, user_name as userName, files.owner, display_name as displayName
      FROM users
      JOIN user_access ON user_access.user_id = users.id
      JOIN files ON files.id = user_access.file_id
-     WHERE files.id = ? and (files.owner = ? OR 1 = ?)`,
-    [fileId, userId, isAdmin ? 1 : 0],
+     WHERE files.id = ?${isAdmin ? '' : ' AND files.owner = ?'}`,
+    isAdmin ? [fileId] : [fileId, userId],
   );
 }

This refactoring improves readability and removes the unconventional use of 1 = ? in the WHERE clause.
