Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for langchain-experimental, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update langchain-experimental to 0.0.61 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-wmvm-9vqv-5qpp is resolved across your whole dependency graph.
Workarounds
Close the privilege gap rather than the entry point: audit which accounts, roles and service identities can reach the affected operation, drop the component to the least privilege it actually needs, and review file and directory permissions created by earlier installs — a default left in place is what makes this reachable.
