In reachable deployments, unauthenticated pre-start sockets could be held open and increase resource pressure.\n\n### Affected Packages / Versions\n- `openclaw` (npm): vulnerable `<= 2026.2.21-2`, patched in `2026.2.22`.\n- `@openclaw/voice-call` (npm): vulnerable `<= 2026.2.21`, patched in `2026.2.22`.\n\n### Technical Details\nBefore 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.\n\n### Impact\nAvailability 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.\n\n### Remediation\nThe fix adds layered controls in the media-stream path:\n- strict pre-start timeout (close sockets that do not send a valid `start` frame quickly)\n- global pending-connection cap\n- per-IP pending-connection cap\n- total open media-stream connection cap\n- safer upgrade-path parsing in the webhook server\n\n### Fix Commit(s)\n- `1d8968c8a821ff1a05c294a1846b3bcb6f343794`\n\n### Release Process Note\n`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.\n\nOpenClaw thanks @jiseoung for reporting.","state":0,"publishedAt":"2026-03-02T22:39:43+00:00","modifiedAt":"2026-09-10T03:50:39.974855+00:00","affected":[{"ecosystem":"npm","name":"openclaw","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"2026.2.22"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"npm","name":"@openclaw/voice-call","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"2026.2.22"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":null,"severity":null},{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"HIGH"}],"references":["https://github.com/openclaw/openclaw/security/advisories/GHSA-mfg5-7q5g-f37j","https://nvd.nist.gov/vuln/detail/CVE-2026-32062","https://github.com/openclaw/openclaw/commit/1d8968c8a821ff1a05c294a1846b3bcb6f343794","https://github.com/openclaw/openclaw","https://www.vulncheck.com/advisories/openclaw-unauthenticated-websocket-resource-exhaustion-via-media-stream"],"sourceUrl":"https://github.com/advisories/GHSA-mfg5-7q5g-f37j","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-mfg5-7q5g-f37j","identifiers":["GHSA-mfg5-7q5g-f37j","CVE-2026-32062"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
