Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Fix

    Update remdex/livehelperchat to 3.92 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-0266 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
