Security Vulnerability — No Patch Available Yet

aieng-bot fixed the following vulnerabilities automatically:

  • aiohttp 3.13.43.14.1: CVE-2026-34993 (CookieJar.load arbitrary code execution), CVE-2026-47265 (cross-origin cookie leak)
  • pip 26.126.1.2: PYSEC-2026-196 (console script path traversal)

However, the following vulnerability cannot be fixed automatically because no patched version has been released to PyPI yet:

Package Version Vulnerability Status
chromadb 1.5.5 CVE-2026-45829 No fix available on PyPI

Details

CVE-2026-45829 (chromadb 1.5.5): A pre-authentication code injection vulnerability in ChromaDB ≥1.0.0. An unauthenticated attacker can run arbitrary code on the server by sending a malicious model repository with trust_remote_code=true via the /api/v2/tenants/{tenant}/databases/{db}/collections endpoint. No fixed version has been published to PyPI.

Why this cannot be auto-fixed

The vulnerability exists in chromadb itself. A fix requires the upstream maintainers to release a new version. Once a patched release is published to PyPI, aieng-bot can re-run and apply the update automatically.

Recommended next steps

  1. Monitor the chromadb vulnerability advisory for a patch release
  2. Consider whether a temporary pip-audit ignore with justification can be added (requires human review)
  3. Evaluate whether this dependency can be replaced or usage restricted

This PR will not be auto-merged until the vulnerability is resolved.

Security Vulnerability — No Patch Available Yet

aieng-bot found the following security vulnerability reported by pip-audit, but cannot fix it automatically because no patched version has been released to PyPI yet:

Package Version Vulnerability Status
chromadb 1.5.5 CVE-2026-45829 No fix available on PyPI (affects 1.0.0–1.5.9)

Why this cannot be auto-fixed

The vulnerability is a pre-authentication code injection in ChromaDB (versions 1.0.0+). It allows an unauthenticated attacker to run arbitrary code on the server by sending a malicious model repository with trust_remote_code=true to the /api/v2/tenants/{tenant}/databases/{db}/collections endpoint.

The OSV database confirms no fixed version exists — all releases through the latest (1.5.9) remain affected. A fix requires the upstream ChromaDB maintainers to release a patched version.

Recommended next steps

  1. Monitor the CVE-2026-45829 advisory for a patch release
  2. Consider whether a pip-audit ignore/exception can be added temporarily with justification (requires human review)
  3. Evaluate whether the trust_remote_code attack surface is reachable in your deployment

This PR will not be auto-merged until the vulnerability is resolved.

Security Vulnerability — No Patch Available Yet

aieng-bot found the following security vulnerability reported by pip-audit, but cannot fix it automatically because no patched version has been released to PyPI yet:

Package Version Vulnerability Status
chromadb 1.5.5 CVE-2026-45829 No fix available on PyPI (confirmed through 1.5.9)

Why this cannot be auto-fixed

The vulnerability exists in chromadb itself. The CVE describes: "A pre-authentication, code injection vulnerability in version 1.0.0 or later of the ChromaDB Python project allows an unauthenticated attacker to run arbitrary code on the server by sending a malicious model repository and trust_remote_code set to true."

aieng-bot verified that versions 1.5.5 through 1.5.9 (latest) all carry this CVE with no fix version listed in the advisory. A fix requires the upstream ChromaDB maintainers to release a new version.

Recommended next steps

  1. Monitor the CVE-2026-45829 advisory for a patch release from the ChromaDB project
  2. If this vulnerability is not applicable to your deployment (e.g., trust_remote_code is never set to true), a human reviewer can add CVE-2026-45829 to the ignore-vulns list in .github/workflows/code_checks.yml with a documented justification
  3. Once a patched chromadb release is published to PyPI, aieng-bot can re-run and apply the update automatically

This PR will not be auto-merged until the vulnerability is resolved.

Security Vulnerability — No Patch Available Yet

aieng-bot found the following security vulnerability reported by pip-audit, but cannot fix it automatically because no patched version has been released to PyPI yet:

Package Version Vulnerability Status
chromadb 1.5.5 CVE-2026-45829 / GHSA-f4j7-r4q5-qw2c No fix available on PyPI

Vulnerability Details

A pre-authentication, code injection vulnerability in chromadb version 1.0.0 or later allows an unauthenticated attacker to run arbitrary code on the server by sending a malicious model repository with trust_remote_code set to true in the /api/v2/tenants/{tenant}/databases/{db}/collections endpoint.

Why this cannot be auto-fixed

The PyPI vulnerability advisory for CVE-2026-45829 lists fixed_in: [] — no version of chromadb has been marked as containing a fix. The latest available version (1.5.9) does not appear in the advisory's fix list. A fix requires the chromadb upstream maintainers to release a patched version.

Recommended next steps

  1. Monitor the GHSA-f4j7-r4q5-qw2c advisory for a patch release
  2. Once a patched release is published to PyPI, aieng-bot can re-run and apply the update automatically
  3. Consider whether a temporary pip-audit ignore/exception can be added with justification (requires human review)

This PR will not be auto-merged until the vulnerability is resolved.

Security Vulnerability — No Patch Available Yet

aieng-bot found the following security vulnerability reported by pip-audit, but cannot fix it automatically because no patched version has been released to PyPI yet:

Package Version Vulnerability Status
chromadb 1.5.5 CVE-2026-45829 No fix available on PyPI (affects all versions ≥ 1.0.0, up to and including latest 1.5.9)

Why this cannot be auto-fixed

The vulnerability is a pre-authentication code injection vulnerability in chromadb itself. According to the OSV advisory (GHSA-f4j7-r4q5-qw2c), all versions from 1.0.0 through 1.5.9 (the current latest) are affected and no fixed version has been published to PyPI yet. A fix requires the upstream ChromaDB maintainers to release a new version.

Recommended next steps

  1. Monitor the vulnerability advisory for a patch release
  2. Check if a pip-audit ignore/exception can be added temporarily with justification (requires human review)
  3. Consider whether this dependency can be replaced with an alternative

This PR will not be auto-merged until the vulnerability is resolved.

Security Vulnerability — No Patch Available Yet

aieng-bot found the following security vulnerability reported by pip-audit, but cannot fix it automatically because no patched version has been released to PyPI yet:

Package Version Vulnerability Status
chromadb 1.5.5 CVE-2026-45829 (GHSA-f4j7-r4q5-qw2c) No fix available on PyPI

Why this cannot be auto-fixed

The vulnerability is a pre-authentication code injection flaw in ChromaDB (CRITICAL severity). According to the OSV advisory, all versions from 1.0.0 through 1.5.9 (the current latest on PyPI) are affected — the range uses last_affected: 1.5.9 with no fixed version listed, meaning the ChromaDB maintainers have not yet released a patched version to PyPI.

Bumping chromadb from 1.5.5 to 1.5.9 would not resolve the vulnerability.

Recommended next steps

  1. Monitor GHSA-f4j7-r4q5-qw2c and the upstream issue for a patch release
  2. Once a patched release is published to PyPI, aieng-bot can re-run and apply the update automatically
  3. Consider whether a pip-audit ignore/exception can be added temporarily with justification (requires human review)

This PR will not be auto-merged until the vulnerability is resolved.

Security Vulnerabilities — Partial Fix + Remaining Unfixable Issues

aieng-bot applied fixes for 5 packages (cryptography, pypdf, langsmith, msgpack, pydantic-settings) but the following vulnerabilities cannot be auto-fixed due to incompatible dependency constraints:

Fixed ✅

Package Old Version New Version Vulnerability
pypdf 6.12.0 6.13.3 CVE-2026-48735, CVE-2026-49461, CVE-2026-49460, CVE-2026-54531, CVE-2026-54530, GHSA-jm82-fx9c-mx94
cryptography 46.0.7 49.0.0 GHSA-537c-gmf6-5ccf
langsmith 0.8.0 0.8.18 GHSA-f4xh-w4cj-qxq8
msgpack 1.1.2 1.2.1 GHSA-6v7p-g79w-8964
pydantic-settings 2.13.1 2.14.2 GHSA-4xgf-cpjx-pc3j

Unfixable — Human Review Required ⚠️

Package Version Vulnerability Reason Cannot Fix
chromadb 1.5.5 CVE-2026-45829 No patched version available on PyPI
langchain 0.3.30 GHSA-gr75-jv2w-4656 Fix requires langchain>=1.3.9 but incompatible with langchain-graphrag (numpy<2.0.0) and langchain-neo4j constraints
langchain-openai 0.3.35 PYSEC-2026-76 Fix requires langchain-openai>=1.1.14 (langchain 1.x ecosystem, same numpy conflict)
langchain-text-splitters 0.3.11 PYSEC-2026-77 Fix requires langchain-text-splitters>=1.1.2 (langchain 1.x ecosystem, same numpy conflict)
langgraph 0.5.0 PYSEC-2026-83 Fix requires langgraph>=1.0.10 (langchain 1.x ecosystem, same numpy conflict)

Why the langchain ecosystem cannot be upgraded

Bumping langchain to 1.x causes an unsatisfiable dependency conflict:

  • langchain-graphrag>=0.0.9 requires numpy<2.0.0
  • langchain-neo4j>=0.7.0 (required by langchain 1.x path) requires neo4j-graphrag>=1.12.0 which requires numpy>=2.0.0

This conflict is irreconcilable until either langchain-graphrag is updated to support numpy 2.x or an alternative dependency path exists.

Recommended next steps

  1. Update or replace langchain-graphrag to support numpy>=2.0.0
  2. Then the full langchain 1.x ecosystem upgrade can be applied
  3. For chromadb CVE-2026-45829: monitor upstream for a patched release, or consider adding to the pip-audit ignore list with justification if the attack surface is not applicable to this project's deployment

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

Security Vulnerabilities — Cannot Be Auto-Fixed

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

Package Version Vulnerability Fix Version Status
chromadb 1.5.5 CVE-2026-45829 None No fix available on PyPI
langchain 0.3.30 GHSA-gr75-jv2w-4656 1.3.9 Fix blocked by dependency conflict

Why these cannot be auto-fixed

chromadb CVE-2026-45829: A pre-authentication code injection vulnerability affecting ChromaDB 1.0.0+. pip-audit reports no fixed version — the latest PyPI release (1.5.9) is still listed as affected.

langchain GHSA-gr75-jv2w-4656: A path traversal vulnerability fixed in langchain 1.3.9. However, upgrading to 1.3.9 requires langchain-neo4j ≥ 0.7.0, which in turn requires neo4j-graphrag with numpy ≥ 2.0.0. This conflicts with langchain-graphrag's dependency on graspologic, which requires numpy < 2.0.0. The dependency graph is unsatisfiable with the current package set.

Recommended next steps

  1. chromadb: Monitor the CVE-2026-45829 advisory for an upstream patch. Once a fixed release appears on PyPI, aieng-bot can apply it automatically.
  2. langchain: Consider whether langchain-graphrag can be upgraded to a version that supports numpy ≥ 2.0.0 (a graspologic pre-release 3.4.5.dev2 exists but is not stable), or evaluate alternative packages. Once the numpy conflict is resolved, langchain can be bumped to ≥ 1.3.9.

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

Security Vulnerabilities — Cannot Be Auto-Fixed

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 exists (1.3.9) but incompatible dependencies block upgrade

CVE-2026-45829 — chromadb 1.5.5

A pre-authentication code injection vulnerability affecting chromadb ≥ 1.0.0 when trust_remote_code=True is set. pip-audit reports no patched version is available on PyPI. The latest release (1.5.9) does not fix this issue.

Why it cannot be auto-fixed: No patched version has been released upstream.

GHSA-gr75-jv2w-4656 — langchain 0.3.30

A path traversal / sandbox escape vulnerability. The fix requires upgrading to langchain ≥ 1.3.9 (a major version bump from 0.3.x to 1.x).

Why it cannot be auto-fixed: Upgrading langchain to 1.x requires langchain-neo4j ≥ 0.6.0, which requires neo4j-graphrag ≥ 1.9.0 (needs numpy ≥ 2.0.0). However, langchain-graphrag 0.0.9 requires graspologic ≥ 3.4.1, which requires numpy < 2.0.0 — an irreconcilable conflict in the current dependency tree.

To fix this, upstream langchain-graphrag (currently pinned at 0.0.9, the only available release) needs to be updated to support graspologic with numpy ≥ 2.0.0.

Recommended next steps

  1. Monitor langchain-graphrag for a new release that supports numpy 2.x
  2. Once available, the full upgrade path is: bump langchain≥1.3.9, langchain-neo4j≥0.6.0, and update langchain-graphrag
  3. Consider whether langchain-graphrag can be replaced with an alternative that supports numpy 2.x
  4. For chromadb, monitor CVE-2026-45829 for an upstream fix

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