{"id":"CVE-2022-29235","state":"PUBLISHED","title":"Limited data exposure for shared external videos in BigBlueButton","description":"BigBlueButton is an open source web conferencing system. Starting in version 2.2 and prior to versions 2.3.18 and 2.4-rc-6, an attacker who is able to obtain the meeting identifier for a meeting on a server can find information related to an external video being shared, like the current timestamp and play/pause. The problem has been patched in versions 2.3.18 and 2.4-rc-6 by modifying the stream to send the data only for users in the meeting. There are currently no known workarounds.","publishedAt":"2022-06-01T23:25:18.000Z","updatedAt":"2024-08-03T06:17:54.233Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["bigbluebutton bigbluebutton"],"affected":[{"vendor":"bigbluebutton","product":"bigbluebutton","versions":[{"version":">= 2.2, < 2.3.18","status":"affected"},{"version":">= 2.4-alpha-1, < 2.4-rc-6","status":"affected"}]}],"references":["https://github.com/bigbluebutton/bigbluebutton/security/advisories/GHSA-x82p-j22f-v4q6","https://github.com/bigbluebutton/bigbluebutton/pull/13788","https://github.com/bigbluebutton/bigbluebutton/pull/14265","https://github.com/bigbluebutton/bigbluebutton/releases/tag/v2.3.18","https://github.com/bigbluebutton/bigbluebutton/releases/tag/v2.4-rc-6"],"weaknesses":["CWE-200"],"ingestedAt":"2026-10-29T19:49:57.813Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2022/29xxx/CVE-2022-29235.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2022-29235","state":"PUBLISHED","datePublished":"2022-06-01T23:25:18.000Z","dateUpdated":"2024-08-03T06:17:54.233Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2022-04-13T00:00:00.000Z"},"containers":{"cna":{"title":"Limited data exposure for shared external videos in BigBlueButton","descriptions":[{"lang":"en","value":"BigBlueButton is an open source web conferencing system.
