{"id":"CVE-2022-29235","summary":"Limited data exposure for shared external videos in BigBlueButton","details":"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.","aliases":["GHSA-x82p-j22f-v4q6"],"modified":"2026-08-12T03:51:46.221474547Z","published":"2022-06-01T23:25:18Z","database_specific":{"cwe_ids":["CWE-200"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/29xxx/CVE-2022-29235.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/bigbluebutton/bigbluebutton/releases/tag/v2.3.18"},{"type":"WEB","url":"https://github.com/bigbluebutton/bigbluebutton/releases/tag/v2.4-rc-6"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/29xxx/CVE-2022-29235.json"},{"type":"ADVISORY","url":"https://github.com/bigbluebutton/bigbluebutton/security/advisories/GHSA-x82p-j22f-v4q6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-29235"},{"type":"FIX","url":"https://github.com/bigbluebutton/bigbluebutton/pull/13788"},{"type":"FIX","url":"https://github.com/bigbluebutton/bigbluebutton/pull/14265"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/bigbluebutton/bigbluebutton","events":[{"introduced":"68e35c9d722e62892d2e885646a9eab3bf44f77d"},{"fixed":"0bcb8c2b9e850b99faae7fcfb3d1014e64bff97d"},{"fixed":"07cfcd376a44aceb543bcb8f098cf34d73b6b8bf"}],"database_specific":{"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:bigbluebutton:bigbluebutton:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"2.2.0"},{"fixed":"2.3.18"}]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-29235.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"}]}
