🛡️ Sentinel: [MEDIUM] Fix information disclosure in ingest route

[socialawy-dev]

🚨 Severity: MEDIUM
💡 Vulnerability: The /projects/{project_id}/ingest endpoint in src/audioformation/server/routes.py directly returned unhandled exception details (str(e)) in the HTTPException detail field when a file upload failed. This could potentially expose sensitive internal file paths, library versions, or system state to a client.
🎯 Impact: Exposing raw exception messages can aid an attacker by revealing internal directory structures and the libraries/tools in use, which could be chained to exploit further vulnerabilities.
🔧 Fix:

• Modified the exception block in ingest_files to log the actual error message internally using logger.error().
• Raised the HTTPException with a generic detail="Upload failed" message to fail securely.
• Also enhanced the validate_path_within helper in src/audioformation/utils/security.py to gracefully catch TypeError and AttributeError for malformed inputs, ensuring further robustness against exception-based disclosure or unexpected errors in path validation.
• Recorded the findings in the .jules/sentinel.md journal.
  ✅ Verification:
• The full test suite and lint checks ran and passed successfully.
• Code conforms to defense-in-depth principles by logging sensitive info to the backend and failing securely on the frontend.

Code Review

This pull request addresses an information disclosure vulnerability in the ingest route by sanitizing error messages returned to the client and logging the actual errors internally. It also enhances path validation security by catching additional exception types and updates dependency versions. Feedback was provided regarding a likely typo in the ruff version within the lock file and a suggestion to use logger.exception() for better error tracking in the server routes.

[gemini-code-assist]

The version specifier 0.15.1 for ruff appears to be a typo. Ruff versions currently follow a 0.x.y format, and the 0.1.x series ended at 0.1.15, while the current series is at 0.9.x. This invalid version will likely cause dependency resolution to fail. If you intended to update to a newer version, please verify the correct version number (e.g., 0.1.15 or a recent 0.9.x release). Furthermore, manually editing uv.lock is generally discouraged; it is better to update pyproject.toml and let the package manager regenerate the lock file.

[gemini-code-assist]

When handling exceptions that result in a 500 Internal Server Error, it is more idiomatic and useful to use logger.exception(). This method automatically captures the full stack trace, which is essential for debugging the root cause of the failure. Additionally, using logger.exception("Upload failed") is preferred over f-strings for the log message to allow for cleaner logging and better integration with logging aggregators.

Suggested change

	logger.error(f"Upload failed: {e}")
	logger.exception("Upload failed")
