{"id":"CVE-2025-55200","summary":"BigBlueButton vulnerable to Stored XSS via name of user at Shared Notes","details":"BigBlueButton is an open-source virtual classroom. In versions prior to 3.0.13, the \"Shared Notes\" feature contains a Stored Cross-Site Scripting (XSS) vulnerability with the input location being the \"Username\" field and the output location on the \"Shared Notes\" page, when a user with a malicious username is editing content. This vulnerability allows a low-privileged user to execute arbitrary JavaScript in the context of higher-privileged users (e.g., Admins) who open the Shared Notes page. Version 3.0.13 fixes the issue.","aliases":["GHSA-9jv9-cjrm-grj2"],"modified":"2026-04-10T05:32:15.328065Z","published":"2025-10-09T18:51:57.884Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/55xxx/CVE-2025-55200.json","cwe_ids":["CWE-79"],"cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/bigbluebutton/bbb-pads/releases/tag/v1.5.4"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/55xxx/CVE-2025-55200.json"},{"type":"ADVISORY","url":"https://github.com/bigbluebutton/bigbluebutton/security/advisories/GHSA-9jv9-cjrm-grj2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-55200"},{"type":"FIX","url":"https://github.com/bigbluebutton/bbb-pads/pull/67"},{"type":"FIX","url":"https://github.com/bigbluebutton/bigbluebutton/pull/23693"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/bigbluebutton/bbb-pads","events":[{"introduced":"0"},{"fixed":"611795205c55e0a034d0d438efe7802a76aaee7f"}]}],"versions":["v1.0.0","v1.0.1","v1.0.2","v1.5.2","v1.5.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-55200.json"}},{"ranges":[{"type":"GIT","repo":"https://github.com/bigbluebutton/bigbluebutton","events":[{"introduced":"0"},{"fixed":"2004667668f7bbb29aa235943275ee76226bad4d"}]}],"versions":["2.2-beta-10","2.2-beta-11","2.2-beta-12","2.2-beta-14","2.2-beta-15","2.2-beta-16","2.2-beta-17","2.2-beta-18","2.2-beta-19","2.2-beta-2","2.2-beta-20","2.2-beta-21","2.2-beta-22","2.2-beta-23","2.2-beta-3","2.2-beta-4","2.2-beta-5","2.2-beta-6","2.2-beta-7","2.2-beta-8","2.2-beta-9","2.2-rc-1","2.2-rc-2","2.2-rc-3","3.0.0-rc.1","dcs-2-a","v0.8","v0.8b4","v0.8b4.0","v0.8rc2","v0.9.0-beta","v2.3-alpha-1","v2.3-alpha-2","v2.3-alpha-3","v2.3-alpha-4","v2.3-alpha-5","v2.3-alpha-6","v2.3-alpha-7","v2.3-alpha-8","v2.3-beta-1","v2.3-beta-2","v2.3-beta-3","v2.3-beta-4","v2.3-beta-5","v2.3-rc-1","v2.3-rc-2","v2.3.0","v2.3.1","v2.4-alpha-1","v2.4-beta-1","v2.4-beta-2","v2.4-beta-3","v2.4-beta-4","v3.0.0","v3.0.0-alpha.1","v3.0.0-alpha.2","v3.0.0-alpha.3","v3.0.0-alpha.4","v3.0.0-alpha.6","v3.0.0-alpha.7","v3.0.0-beta.1","v3.0.0-beta.2","v3.0.0-beta.3","v3.0.0-beta.4","v3.0.0-beta.5","v3.0.0-beta.6","v3.0.0-beta.7","v3.0.0-rc.1","v3.0.0-rc.2","v3.0.0-rc.3","v3.0.0-rc.4","v3.0.1","v3.0.10","v3.0.11","v3.0.12","v3.0.2","v3.0.3","v3.0.4","v3.0.5","v3.0.7","v3.0.8","v3.0.9"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-55200.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N"}]}
