Description

openssl-encrypt's readiness endpoint leaks database error details to unauthenticated callers

Summary

The /ready endpoint in openssl_encrypt_server/server.py at lines 159-175 catches database errors and returns the full exception string in the response.

Affected Code

except Exception as e:
    return {"status": "not_ready", "reason": str(e)}

Impact

Database exception messages can leak:

Database hostnames and IP addresses

Connection parameters and port numbers

Driver version information

Potentially database credentials if included in connection string errors

This information is available to unauthenticated callers.

Recommended Fix

Return a generic error message: {"status": "not_ready", "reason": "database unavailable"}

Log the full exception server-side for debugging

Fix

Fixed in commit 7aa8787 on branch releases/1.4.x — replaced str(e) with generic "database check failed" message; full exception logged server-side at WARNING level.

Mitigation
