Estimated code review effort: 2 (Simple) | ~10 minutes Severity of issue fixed: Medium Merge Risk: 🟡 Moderate · up to The service now returns fixed LLM errors, but failure tracebacks can still retain sensitive provider or infrastructure details in logs.

Sensitive Data Exposure
Reachability: External
Exploitability: Difficult
CWE: CWE-532 — Insertion of Sensitive Information into Log File
Redact exception details before logging LLM failures.
All four handlers use exc_info=True, which includes exception text and chained causes in formatted tracebacks. The fixed LLMServiceError message protects the API response, but not the log sink. Add redaction at the logging boundary, or log only a static message with safe metadata. Update .jules/sentinel.md to state that unfiltered exc_info=True is not sufficient.

#1612@3da3ae8e60e1bb049f59ae86bfe82db12b7e3cc7cf1c01b50e2f2310a802e77aa143604d13d0fbb80d15766369f3830080f86f63cfbb5eda7a180b1695c0ddf56d4e86d1abeeaf7387486180b7b5feecThe generated finding had a valid core intent: raw provider exception text must not escape through Naruon logs or user-facing
LLMServiceErrormessages. The generated implementation was not a sufficient security repair.logger.error("...", exc_info=True)still records the active exception traceback and original message, so secret-bearing provider/network text can remain in logs. Likewiseraise LLMServiceError("...") from epreserves the sensitive original exception object as__cause__. The generated.jules/sentinel.mdguidance recommended those same unsafe patterns and is therefore rejected rather than transferred.Canonical #1612 already owns this boundary more completely in
backend/services/llm_service.pyand shared safe-logging/tests: it usesredacted_exception_info(exc)for diagnostic logging and raises the genericLLMServiceErrorfromNone, with regressions covering logs plus exception cause/context leakage. #1612 itself remains subject to its existing shared required-gate blockers; closing this duplicate does not authorize #1612 merge.The generated branch also advanced with
.trivyignoreentries forCVE-2026-75604,GHSA-2xp9-vwfh-vxw4, andGHSA-rgj7-g3m4-5g8c. Those exceptions are not accepted. Frontend dependency-security remediation remains owned by #1623.Ordinary two-parent
95c0ddf...preserved the complete generated/intervening history as first-parent provenance, adopted exact #1612 as second parent, and pointed to #1612's exact tree. Fresh compare then proved zero effective delta. This satisfies the complete-successor closure condition: all valid security intent is present in the stronger canonical successor, while the only unique generated changes are explicitly rejected unsafe guidance/security exceptions.No merge, force push, destructive rebase, security-ignore transfer, duplicate logging implementation, self-approval, or gate weakening was used.
