Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for zendframework/zendframework1, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update zendframework/zendframework1 to 1.12.16 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2015-7695 is resolved across your whole dependency graph.

  3. 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.
