Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Fix

    Update admidio/admidio to 4.2.9 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-x3m2-3pwj-8fj4 is resolved across your whole dependency graph.

  3. Workarounds

    Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
