+## Input from Untrusted Sources
+
+If your application accepts input from untrusted sources (such as query parameters from HTTP requests) please ensure you are following best practices for data validation and sanitization. It is your application's responsibility to ensure any data provided to the SDK is valid and safe. For more information, see the [OWASP Data Validation Cheat Sheet](https://cheatsheetseries.owasp.org/cheatsheets/Input_Validation_Cheat_Sheet.html).
