Description

Summary

Incomplete fix for CVE-2026-32062: voice-call still parses large WebSocket frames before start validation

Current Maintainer Triage

  • Normalized severity: medium
  • Assessment: v2026.3.28 still parses oversized pre-start voice-call WebSocket frames before start validation, and the unreleased maxPayload fix confirms the shipped resource-consumption bug remains open.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Latest published npm version: 2026.3.31
  • Vulnerable version range: <=2026.3.28
  • Patched versions: >= 2026.3.31
  • First stable tag containing the fix: v2026.3.31

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openclaw. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update openclaw to 2026.3.31 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-2w79-r9g8-wmcr 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.

  4. How O3 protects you

    O3 pinpoints whether GHSA-2w79-r9g8-wmcr is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-2w79-r9g8-wmcr. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
