{"id":"CVE-2022-41960","state":"PUBLISHED","title":"BigBlueButton contains DoS via failed authToken validation","description":"BigBlueButton is an open source web conferencing system. 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.","publishedAt":"2022-12-15T23:56:26.500Z","updatedAt":"2025-04-17T18:07:27.624Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["bigbluebutton bigbluebutton"],"affected":[{"vendor":"bigbluebutton","product":"bigbluebutton","versions":[{"version":"< 2.4.3","status":"affected"}]}],"references":["https://github.com/bigbluebutton/bigbluebutton/security/advisories/GHSA-rgjp-3r74-g4cm","https://github.com/bigbluebutton/bigbluebutton/releases/tag/v2.4.3","https://github.com/bigbluebutton/bigbluebutton/releases/tag/v2.5-alpha-1"],"weaknesses":["CWE-345"],"ingestedAt":"2026-10-29T19:50:37.819Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2022/41xxx/CVE-2022-41960.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2022-41960","state":"PUBLISHED","datePublished":"2022-12-15T23:56:26.500Z","dateUpdated":"2025-04-17T18:07:27.624Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","requesterUserId":"c184a3d9-dc98-4c48-a45b-d2d88cf0ac74","dateReserved":"2022-09-30T16:38:28.947Z"},"containers":{"cna":{"title":"BigBlueButton contains DoS via failed authToken validation","descriptions":[{"lang":"en","value":"BigBlueButton is an open source web conferencing system.
