Key Changes Explained: Enhanced security checks: Added checks to prevent Path Traversal attacks by verifying that the file name does not contain ".." and is within the list of allowed file names. Improved error handling: Changed the HTTP response codes to more accurately reflect the nature of the error (e.g., returning 404 Not Found for missing files and 403 Forbidden for unauthorized access attempts). Condition validation: Immediately returns a 400 Bad Request if the precondition is not met, which helps in quickly identifying issues with request parameters. Error Logging: Now logs different types of errors distinctly for better diagnostics.Key Changes Explained: Enhanced security checks: Added checks to prevent Path Traversal attacks by verifying that the file name does not contain ".." and is within the list of allowed file names.

There was a problem hiding this comment.
Why this change? we wanted to introduce vulnerability in the application and this will disallow ".." in file name.
