OpenClaw versions 2026.2.21-2 up to, but not including, 2026.2.22, and @openclaw/voice-call versions 2026.2.21 up to, but not including, 2026.2.22 accept media-stream WebSocket upgrades before stream validation, allowing unauthenticated clients to establish connections. Remote attackers can hold idle pre-authenticated sockets open to consume connection resources and degrade service availability for legitimate streams.

### 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 ### Fix Commit(s) - `1d8968c8a821ff1a05c294a1846b3bcb6f343794` ### 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. OpenClaw thanks @jiseoung for reporting.

Exploitation and risk

Source status

CISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.

Which CVEs have scores here?

This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.

No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.
