# 🔥 Burn Report #1 — 2026-03-31 01:15 UTC
|
|
|
|
**Focus Area:** Security (HIGH/CRITICAL Vulnerabilities)
|
|
**Burn Duration:** ~28 minutes
|
|
**Subagents Deployed:** 4
|

|
|
|
|
## Executive Summary
|
|
|
|
Security burn of hermes-agent repository revealed **3 stale/empty security PRs** blocking the merge queue. The actual V-011 vulnerability remains **UNPATCHED**.
|
|

|
## Work Completed
|
|
|
|
### ✅ Reviewed 3 Security PRs
|
|
|
|
| PR | Vuln | CVSS | Status | Finding |
|
|
|----|------|------|--------|---------|
|
|
| #69 | V-011 Skills Guard Bypass | 7.8 HIGH | **EMPTY** | No actual changes - points to already-merged commit |
|
|
| #70 | V-014 OAuth Session Fixation | 7.6 HIGH | **MERGED** | Already in main via PR #68 |
|
|
| #71 | V-015 File TOCTOU | 7.4 HIGH | **MERGED** | Already in main via PR #68 |
|
|
|
|
### ✅ Verified Security Posture
|
|
|
|
- **V-006** (CVSS 8.8 CRITICAL): ✅ Fixed and merged (PR #68)
|
|
- **V-014** (CVSS 7.6 HIGH): ✅ Fixed and merged (PR #68)
|
|
- **V-015** (CVSS 7.4 HIGH): ✅ Fixed and merged (PR #68)
|
|
- **V-011** (CVSS 7.8 HIGH): ❌ **UNPATCHED** - requires implementation
|
|
|
|
### ⚠️ Attempted V-011 Fix Implementation
|
|
|
|
Subagent attempted to implement the V-011 fix including:
|
|
- Unicode NFKC normalization + case folding
|
|
- AST-based analysis for Python code
|
|
- Enhanced threat patterns for Cyrillic homoglyphs, fullwidth chars
|
|
- Dynamic execution pattern detection (globals, locals, __dict__)
|
|
|
|
**Result:** Partial implementation saved to `tools/skills_guard.py.new` but incomplete.

## Critical Finding: V-011 Still Open
|
|
|
|
**Vulnerability:** Skills Guard Bypass via Obfuscation
|
|
**CVSS:** 7.8 (HIGH)
|
|
**Location:** `tools/skills_guard.py`
|
|
|
|
**Issue:** Current regex-based detection can be bypassed with:
|
|
- Unicode encoding tricks (fullwidth characters, Cyrillic homoglyphs)
|
|
- Case manipulation
|
|
- Zero-width characters
|
|
- Dynamic execution obfuscation (`globals()['ev'+'al']`)
|
|
|
|
**Required Fix:**
|
|
1. Add `normalize_input()` with NFKC + case folding + ZWSP removal
|
|
2. Implement `PythonSecurityAnalyzer` AST visitor
|
|
3. Add threat patterns for obfuscated variants
|
|
4. Update `scan_file()` to use normalization + AST analysis
|
|
|

|
## Blockers
|
|
|
|
1. **Token Permissions:** GITEA_TOKEN lacks write access for PR closure/issue creation
|
|
2. **Stale PRs:** #69, #70, #71 remain open despite being empty/already-merged
|
|
3. **V-011 Implementation:** Requires dedicated implementation session
|
|
|
|
---
|
|
|
|
## Next Target
|
|
|
|
**Priority 1:** Implement actual V-011 Skills Guard Bypass fix
|
|
- Branch from main
|
|
- Implement normalize_input() + AST analysis
|
|
- Add comprehensive tests
|
|
- Create proper PR for review
|
|
|
|
**Priority 2:** Request token permissions to close stale PRs
|
|
|

|
|
|
|
## Recommendations
|
|
|
|
1. **Close PRs #69, #70, #71** — they block the merge queue and confuse security status
|
|
2. **Create new branch** `security/v-011-skills-guard-bypass` for actual implementation
|
|
3. **Allocate 30-45 minutes** for proper V-011 implementation with tests
|
|
4. **Update SECURITY_AUDIT_REPORT.md** to reflect current status
