Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for langchain, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update langchain to 0.0.247 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7q94-qpjr-xpgm is resolved across your whole dependency graph.
Workarounds
Until you can upgrade, make sure every query built from user input uses parameterised statements or a prepared-statement API rather than string concatenation, and reduce the database account's privileges so an injected query cannot read or alter data beyond what the feature needs.
