# Patch Next advisory brief: CVE-2024-46946

Advisory: LangChain Experimental Eval Injection vulnerability
IDs: CVE-2024-46946, GHSA-p2qj-r53j-h3xj
Record: https://patchnext.com/advisories/cve-2024-46946 (revision 5, source checked 28 Oct 2026, 06:05 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI langchain-experimental: affected >= 0.1.17, <= 0.3.0

## Suggested inspection (read-only)
- `python -m pip show langchain-experimental`: prints the installed version. Run with the environment that serves production active.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on langchain-experimental.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://osv.dev/vulnerability/GHSA-p2qj-r53j-h3xj (OSV record GHSA-p2qj-r53j-h3xj lists affected ranges: PyPI langchain-experimental >=0.1.17 <=0.3.0)
- Verified: https://github.com/advisories/GHSA-p2qj-r53j-h3xj (GitHub-reviewed advisory GHSA-p2qj-r53j-h3xj lists affected ranges: PyPI langchain-experimental >=0.1.17 <=0.3.0)
