Description

Summary

@openclaw/voice-call (and the bundled copy shipped in openclaw) accepted media-stream WebSocket upgrades before stream validation. In reachable deployments, unauthenticated pre-start sockets could be held open and increase resource pressure.

Affected Packages / Versions

  • openclaw (npm): vulnerable <= 2026.2.21-2, patched in 2026.2.22.
  • @openclaw/voice-call (npm): vulnerable <= 2026.2.21, patched in 2026.2.22.

Technical Details

Before this fix, the voice-call media-stream path upgraded sockets first and ran shouldAcceptStream() after a later start frame. This created a pre-auth window where remote clients could hold idle sockets without call/token validation.

Impact

Availability risk in deployments where the media-stream endpoint is reachable and streaming is enabled. Under sustained abuse, this could consume connection-related resources and degrade service for legitimate streams.

Remediation

The fix adds layered controls in the media-stream path:

  • strict pre-start timeout (close sockets that do not send a valid start frame quickly)
  • global pending-connection cap
  • per-IP pending-connection cap
  • total open media-stream connection cap
  • safer upgrade-path parsing in the webhook server

Release Process Note

patched_versions is pre-set to 2026.2.22 so this advisory is ready to publish once npm [email protected] and @openclaw/[email protected] are released.

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, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update openclaw to 2026.2.22 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-32062 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2026-32062 can be triaged on real exposure rather than presence alone.

Tailored to CVE-2026-32062. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
