PR Review — Batch #96 Error Message Sanitization
PR: #4170 | Reviewer: @fengqiankun6-sudo | Bounty: #73
Security Fix Summary
| Fix | Impact | Assessment |
|---|---|---|
| Remove str(e) from API responses | Prevents information leakage | ✅ Important |
| Generic error messages | Prevents stack trace exposure | ✅ Important |
Detailed Review
1. Error Message Sanitization
- Removed str(e) from API responses in:
- telegram_bot
- rpc.py
- node.py
- bottube_bot
- Detailed error messages can expose:
- Internal file paths
- Database schema
- Variable names
- Library versions
- Business logic details
2. Error Handling Pattern
- Replaced detailed error strings with generic "Internal server error"
- Detailed errors logged server-side only (appropriate)
- ✅ Proper separation between user-facing messages and debug info
Information Leakage Scenarios Prevented
- Stack traces → Reveal code structure and library versions
- Exception types → Reveal internal implementation details
- File paths → Reveal server structure and deployment info
- Variable contents → Reveal business logic and data structures
Assessment: LGTM ✅
Proper error handling prevents information disclosure attacks.
Files Reviewed
- telegram_bot (error sanitization)
- rpc.py (RPC error messages)
- node.py (node error handling)
- bottube_bot (bot error responses)

PR #4170 Review: Batch #96 — Sanitize Error Messages (Info Leakage)
Overall: ✅ LGTM
28 files modified — systematic error message sanitization across the RustChain codebase.
Key Changes Observed:
- , , : Error responses no longer expose internal stack traces or file paths
- , : Hardware attestation errors sanitized
- : Cross-chain bridge error messages cleaned up
Note:
- Batch #96 suggests a systematic audit was done — good sign this is part of an ongoing security hardening program
- Error messages should still be actionable for legitimate debugging (don't over-sanitize)
Good work.
