Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for software.amazon.jdbc:aws-advanced-jdbc-wrapper, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update software.amazon.jdbc:aws-advanced-jdbc-wrapper to 2.6.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7xw4-g7mm-r4hh is resolved across your whole dependency graph.

  3. 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.
