{"id":"CVE-2025-61601","summary":"BigBlueButton vulnerable to DoS via PollSubmitVote GraphQL mutation","details":"BigBlueButton is an open-source virtual classroom. A Denial of Service (DoS) vulnerability in versions prior to 3.0.13 allows any authenticated user to freeze or crash the entire server by abusing the polling feature's `Choices` response type. By submitting a malicious payload with a massive array in the `answerIds` field, the attacker can cause the current meeting — and potentially all meetings on the server — to become unresponsive. Version 3.0.13 contains a patch. No known workarounds are available.","aliases":["GHSA-73j3-v3fq-fqx5"],"modified":"2026-07-15T01:49:02.483087510Z","published":"2025-10-09T20:29:25.006Z","database_specific":{"cwe_ids":["CWE-703"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/61xxx/CVE-2025-61601.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://www.youtube.com/watch?v=BwROSVIYjOY"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/61xxx/CVE-2025-61601.json"},{"type":"ADVISORY","url":"https://github.com/bigbluebutton/bigbluebutton/security/advisories/GHSA-73j3-v3fq-fqx5"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-61601"},{"type":"FIX","url":"https://github.com/bigbluebutton/bigbluebutton/pull/23662"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/bigbluebutton/bigbluebutton","events":[{"introduced":"0"},{"fixed":"2004667668f7bbb29aa235943275ee76226bad4d"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"3.0.13"}],"source":["AFFECTED_FIELD","CPE_RANGE"],"cpe":"cpe:2.3:a:bigbluebutton:bigbluebutton:*:*:*:*:*:*:*:*"}}],"versions":["v3.0.12","v3.0.11","v3.0.8","v3.0.10","v3.0.9","v3.0.7","v3.0.5","v3.0.4","v3.0.2","v3.0.3","v3.0.0","v3.0.1","v3.0.0-rc.4","v3.0.0-rc.3","v3.0.0-rc.2","v3.0.0-rc.1","3.0.0-rc.1","v3.0.0-beta.7","v3.0.0-beta.6","v3.0.0-beta.5","v3.0.0-beta.4","v3.0.0-beta.3","v3.0.0-beta.2","v3.0.0-beta.1","v3.0.0-alpha.7","v3.0.0-alpha.6","v3.0.0-alpha.4","v3.0.0-alpha.3","v3.0.0-alpha.2","v3.0.0-alpha.1","v2.4-beta-4","v2.4-beta-3","v2.4-beta-2","v2.4-beta-1","v2.4-alpha-1","v2.3.1","v2.3.0","v2.3-rc-2","v2.3-rc-1","v2.3-beta-5","v2.3-beta-4","v2.3-beta-3","v2.3-beta-2","v2.3-beta-1","v2.3-alpha-8","v2.3-alpha-7","v2.3-alpha-6","v2.3-alpha-5","v2.3-alpha-4","v2.3-alpha-3","v2.3-alpha-2","v2.3-alpha-1","2.2-rc-3","2.2-rc-2","2.2-rc-1","2.2-beta-23","2.2-beta-22","2.2-beta-21","2.2-beta-20","2.2-beta-19","2.2-beta-18","2.2-beta-17","2.2-beta-16","2.2-beta-15","2.2-beta-14","2.2-beta-12","2.2-beta-11","2.2-beta-10","2.2-beta-9","2.2-beta-8","2.2-beta-7","2.2-beta-6","2.2-beta-5","2.2-beta-4","2.2-beta-3","2.2-beta-2","dcs-2-a","v0.9.0-beta","v0.8","v0.8rc2","v0.8b4.0","v0.8b4"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-61601.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
