🛡️ Sentinel: MEDIUM Fix Information Leakage#114
Conversation
🚨 Severity: MEDIUM 💡 Vulnerability: The exception handling block directly passed exception details `str(e)` to the client via `HTTPException`, which could expose internal paths, stack traces, and system configuration. 🔧 Fix: Sanitized the HTTP response by returning a generic "Internal server error" message. The detailed exception is now safely logged to standard output for server administrators. ✅ Verification: Start the local inference server and intentionally trigger an internal error (e.g. by passing an incorrectly structured prompt or breaking the model). The client will receive an "Internal server error" while the backend logs the specific Python traceback. Co-authored-by: daggerstuff <261005129+daggerstuff@users.noreply.github.com>

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |

Reviewer's GuideSanitizes error handling in the local inference API so that internal exception details are no longer returned to clients, while preserving diagnostics via server-side logging, and adds a Sentinel note documenting the information-leakage fix.

There was a problem hiding this comment.
Hey - I've left some high level feedback:
- Instead of printing errors to stdout in the
chat_completionexception handler, consider using your application's structured logging facility (e.g.,loggingwith appropriate level and context) so these internal errors are easier to aggregate and monitor in production. - The broad
except Exception as einchat_completioncould be narrowed to expected error types (e.g., model invocation errors or validation issues), with a separate catch-all that logs and returns the generic 500, to avoid masking distinct error conditions.
