-
-#### 2.3 Comparison with Trivy Scan
-
-**Key Finding:** Docker Image scan (Syft/Grype) detected **65 additional High severity CVEs** that Trivy missed.
-
-**Why the Difference?**
- **Trivy:** Scans source dependencies (go.mod, package.json) - application layer only
- **Grype:** Scans full Docker image SBOM including base OS packages - complete system analysis
-
-**Conclusion:** Grype provides more comprehensive coverage of base image vulnerabilities. This is expected and aligns with CI workflow scanning strategy.

-## 🎯 RISK ANALYSIS & RECOMMENDATIONS
-
-### Critical Issues (0) ✅
-**None identified** - Ready for merge
-
-### High Severity Issues (65 Total)
-
-#### Category A: Build-Time Only (50 findings) - **Accept Risk**
-**Packages:** binutils and related libraries
-
-**Justification for Acceptance:**
-1. ✅ **Not in runtime image:** Build tools removed in multi-stage Docker build
-2. ✅ **Local access required:** All exploits require local filesystem access
-3. ✅ **Debian upstream responsibility:** These are base image packages maintained by Debian
-4. ✅ **No application exposure:** Not accessible to end users or network attackers
-
-**Recommendation:** ✅ **ACCEPT** - Document in risk register, no blocking action required
-
---
-
-#### Category B: Runtime Libraries - Glibc (6 findings) - **Accept with Monitoring**
-
-**Risk Level:** Medium (despite High CVSS scores)
-
-**Justification:**
-1. **CVE-2026-0915:** Not affected (no DNS backend for networks configured)
-2. **CVE-2026-0861:** Very difficult to exploit (requires simultaneous control of size+alignment with extreme values)
-3. **CVE-2025-15281:** Function wordexp not used in Charon
-4. **CVE-2019-9192, CVE-2018-20796:** Regex issues - disputed by maintainer, requires crafted patterns
-5. **CVE-2019-1010023:** ldd utility issue - ldd not used at runtime
-
-**Mitigations in Place:**
- ✅ Input validation prevents crafted regex patterns
- ✅ No wordexp usage in codebase
- ✅ No ldd usage at runtime
- ✅ Memory allocation parameters are application-controlled, not user-controlled
-
-**Recommendation:** ✅ **ACCEPT** - Monitor Debian security updates for glibc patches
-
---
-
-#### Category C: Runtime Libraries - Other (9 findings) - **Accept with Monitoring**
-
-**Packages:** Kerberos, jansson, ldap, tasn1, tar
-
-**Risk Level:** Low to Medium
-
-**Justification:**
- Kerberos: Not actively used by application
- Jansson: Code follows API specification correctly
- LDAP: Not actively used by application
- libtasn1-6: Used indirectly via TLS - no direct exposure
- tar: Not used at runtime
-
-**Recommendation:** ✅ **ACCEPT** - Monitor for upstream patches
