Security Vulnerabilities — Partial Fix Applied

aieng-bot applied patches for all vulnerabilities where a fix was available:

Package Version Vulnerability Fix Applied
aiohttp 3.13.4 → 3.14.1 CVE-2026-34993 + 10 others ✅ Fixed
cryptography 46.0.7 → 48.0.1 GHSA-537c-gmf6-5ccf ✅ Fixed
langsmith 0.8.0 → 0.8.18 GHSA-f4xh-w4cj-qxq8 ✅ Fixed
pydantic-settings 2.13.1 → 2.14.2 GHSA-4xgf-cpjx-pc3j ✅ Fixed
pypdf 6.10.2 → 6.13.3 CVE-2026-48155 + 7 others ✅ Fixed
pip 26.1 → 26.1.2 PYSEC-2026-196 ✅ Fixed

Remaining Vulnerabilities — Cannot Auto-Fix

The following vulnerabilities cannot be fixed automatically and require human review:

1. chromadb — CVE-2026-45829 (No upstream fix)

  • Package: chromadb 1.5.5
  • Issue: Pre-authentication code injection vulnerability (affects all versions ≥ 1.0.0)
  • Status: No patched version has been released to PyPI yet
  • Action needed: Monitor upstream for a fix release

2. LangChain ecosystem — Requires major version upgrade with dependency conflicts

  • Package: langchain 0.3.30 — GHSA-gr75-jv2w-4656 (fix: 1.3.9)
  • Package: langchain-openai 0.3.35 — PYSEC-2026-76 (fix: 1.1.14)
  • Package: langchain-text-splitters 0.3.11 — PYSEC-2026-77 (fix: 1.1.2)
  • Package: langgraph 0.5.0 — PYSEC-2026-83 (fix: 1.0.10)

Why this cannot be auto-fixed: Upgrading these packages to their 1.x fix versions requires a coordinated LangChain ecosystem upgrade. However, this creates an unresolvable dependency conflict for Python 3.12 on Windows (within the project's requires-python = ">=3.10,<3.13" range):

  • langchain>=1.x requires langchain-neo4j>=0.6.0
  • langchain-neo4j>=0.7.0 requires neo4j-graphrag>=1.12.0 → numpy>=2.0.0
  • langchain-graphrag>=0.0.9 (pinned at latest) requires numpy<2.0.0
  • Result: numpy version conflict makes the dependency graph unsatisfiable

Recommended next steps

  1. Upgrade langchain-graphrag to a version that supports numpy>=2.0.0 (none available yet — latest is 0.0.9)
  2. OR restrict requires-python to exclude the conflicting Python version/platform
  3. OR consider replacing langchain-graphrag with an alternative that's compatible with the newer LangChain ecosystem
  4. For chromadb, monitor the CVE-2026-45829 advisory for an upstream patch

This PR will not be auto-merged until the remaining vulnerabilities are resolved.

Re-verification: Security Vulnerabilities Remain Unfixable

aieng-bot re-ran the fix loop and re-confirmed that the 2 remaining vulnerabilities cannot be patched automatically:

1. chromadb — CVE-2026-45829

  • Latest PyPI release is 1.5.9; pip-audit reports no fix version for this CVE
  • The vulnerability affects all chromadb ≥ 1.0.0 — no patched release available

2. langchain — GHSA-gr75-jv2w-4656 (fix: 1.3.9)

The upgrade path is blocked by an irresolvable numpy version conflict:

Requirement Package numpy constraint
langchain ≥ 1.3.9 → langchain-neo4j ≥ 0.6.0
langchain-neo4j ≥ 0.6.0 → neo4j-graphrag ≥ 1.9.0 numpy ≥ 2.0.0
langchain-graphrag 0.0.9 (latest) → graspologic 3.4.4 (latest) numpy < 2.0.0

These constraints are mutually exclusive. No newer version of graspologic or langchain-graphrag resolves this conflict.

Next steps for human review

  1. Watch for a graspologic release that supports numpy ≥ 2.0.0 (or a new langchain-graphrag release)
  2. Watch for a chromadb release that patches CVE-2026-45829
  3. If the risk is acceptable, add these CVEs to the ignore-vulns list in .github/workflows/code_checks.yml with a justification comment

aieng-bot has exhausted all automatic fix options. This PR requires human review before merging.

Security Vulnerabilities — No Patch Available

aieng-bot found the following security vulnerabilities reported by pip-audit, but cannot fix them automatically:

Package Version Vulnerability Status
chromadb 1.5.5 CVE-2026-45829 No fix available on PyPI
langchain 0.3.30 GHSA-gr75-jv2w-4656 Fix requires langchain 1.3.9, but upgrade causes irresolvable dependency conflicts with langchain-graphrag and langchain-neo4j

Why these cannot be auto-fixed

CVE-2026-45829 (chromadb): The vulnerability advisory lists no fixed version. The latest available chromadb (1.5.9) is still flagged. A fix requires the upstream chromadb maintainers to release a patched version.

GHSA-gr75-jv2w-4656 (langchain): The fix requires upgrading from langchain 0.3.30 to langchain ≥1.3.9. However, this upgrade creates irresolvable dependency conflicts:

  • langchain-graphrag requires numpy<2.0.0
  • langchain-neo4j ≥0.7.0 (required by langchain 1.x) depends on neo4j-graphrag ≥1.10.0, which requires numpy≥2.0.0

These constraints are mutually exclusive and cannot be satisfied simultaneously.

Recommended next steps

  1. Monitor CVE-2026-45829 for a chromadb patch release
  2. Wait for langchain-graphrag to support numpy ≥2.0.0, or find an alternative package
  3. Consider adding these CVEs to the ignore-vulns list in .github/workflows/code_checks.yml with explicit justification (requires human review/approval)

This PR will not be auto-merged until the vulnerabilities are resolved.
