GHSA-MFG5-7Q5G-F37J
Vulnerability from github – Published: 2026-03-02 22:39 – Updated: 2026-03-11 20:38Summary
@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 in2026.2.22.@openclaw/voice-call(npm): vulnerable<= 2026.2.21, patched in2026.2.22.
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 openclaw@2026.2.22 and @openclaw/voice-call@2026.2.22 are released.
OpenClaw thanks @jiseoung for reporting.
