Versions prior to 2.4.3, are subject to Insufficient Verification of Data Authenticity, resulting in Denial of Service. An attacker can make a Meteor call to `validateAuthToken` using a victim's userId, meetingId, and an invalid authToken. This forces the victim to leave the conference, because the resulting verification failure is also observed and handled by the victim's client. The attacker must be a participant in any meeting on the server. This issue is patched in version 2.4.3. There are no workarounds."}],"source":{"advisory":"GHSA-rgjp-3r74-g4cm","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-03T12:56:38.614Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/bigbluebutton/bigbluebutton/security/advisories/GHSA-rgjp-3r74-g4cm","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/bigbluebutton/bigbluebutton/security/advisories/GHSA-rgjp-3r74-g4cm"},{"name":"https://github.com/bigbluebutton/bigbluebutton/releases/tag/v2.4.3","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/bigbluebutton/bigbluebutton/releases/tag/v2.4.3"},{"name":"https://github.com/bigbluebutton/bigbluebutton/releases/tag/v2.5-alpha-1","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/bigbluebutton/bigbluebutton/releases/tag/v2.5-alpha-1"}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2025-04-17T18:07:07.915922Z","id":"CVE-2022-41960","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-04-17T18:07:27.624Z"}}]}}
