• [High]Do not store secrets in code repositories or configuration files; use a secrets management solution
  The Env field appears to contain configuration values such as secrets, which could be a potential security risk if committed to a code repository and accessed by unauthorized users. Remove any sensitive information from the Env field and instead use a secrets management solution like AWS Secrets Manager or HashiCorp Vault to securely store and manage secrets. Use environment variables or a configuration file to pass these secrets to the application during runtime instead.
• [Medium]Do not include unnecessary fields in data structures
  The Jobs struct contains an Env field which is not used anywhere in the code. This can lead to confusion and unnecessary complexity. Remove the Env field from the Jobs struct.

• [High]Do not store secrets like GITHUB_TOKEN in job environment variables
  Sensitive data like tokens should not be stored in job environment variables which can be accessed in plaintext format. Store the GITHUB_TOKEN as a repository secret which can be accessed by the workflow from the secrets context. Use secrets.GITHUB_TOKEN to reference the token in the workflow.
• [Medium]Ensure all errors provide informative characteristics for logging and alerting
  Errors in the code should provide sufficient details to make it easy to identify the source of the error. Improve the error messages by providing more details about the error which occurred. The error message helps the developer to quickly locate the error.

• [High]Do not expose secrets in code
  Secrets like tokens and passwords should never be stored in plain text in code. Use a secrets management system or environment variables instead of storing secrets in the code itself.
• [Medium]Avoid using default branches as triggers
  Using default branches for triggers like pull requests can increase the chances of triggering unintended builds or tests. Specify a non-default branch as the trigger for workflows
• [Low]Specify exact versions of dependencies
  Using non-specific version ranges for dependencies can cause unexpected behavior, including security vulnerabilities. Specify exact version numbers for dependencies in package.json.

• [High]Don't store secrets as environment variables
  Storing secrets such as access tokens, passwords, or API keys in environment variables is not secure. Any user with access to the environment variables can easily retrieve the secrets. Instead, use a secure secret storage solution such as HashiCorp Vault. Avoid storing secrets as environment variables. Use a secure secret storage solution such as HashiCorp Vault.
• [High]Limit permissions on jobs and repositories
  In this case, permissions were not added to jobs containing the GITHUB_TOKEN. Permissions should be set to limit access to sensitive information such as access tokens, secret keys, repositories, or files. Restrict permissions on jobs to limit access to sensitive information. Only the required permissions should be given to the user or service account.
• [Medium]Never commit secrets or sensitive data to the repository
  Committing secrets or sensitive data creates a security risk because anyone with access to the repository can view this information. Credentials, keys, or tokens should never be committed to the repository. Remove any sensitive data committed to the repository immediately. Use a secure secret storage solution such as HashiCorp Vault to store secrets.
• [Medium]Check for security vulnerabilities in dependencies
  Even though the code is secure, many vulnerabilities result from using vulnerable dependencies. Keep dependencies up to date and check them for known vulnerabilities regularly. Use automated tools such as OWASP Dependency-Check or Snyk to check for known vulnerabilities in dependencies. Upgrade to the latest version or apply patches as soon as possible.
• [Low]Remove unnecessary code comments
  Any sensitive information or debugging information embedded in comments can provide information to an attacker. It is best to keep comments to a minimum and remove any unnecessary or sensitive comments. Remove any unnecessary comments from the codebase, especially if they contain sensitive or security-related information.
