In versions up to and including 26.0, the standalone live stream control endpoint at `plugin/Live/standAloneFiles/control.json.php` accepts a user-supplied `streamerURL` parameter that overrides where the server sends token verification requests. An attacker can redirect token verification to a server they control that always returns `{\"error\": false}`, completely bypassing authentication. This grants unauthenticated control over any live stream on the platform, including dropping active publishers, starting/stopping recordings, and probing stream existence. Commit 388fcd57dbd16f6cb3ebcdf1d08cf2b929941128 contains a patch.","published_at":"2026-03-23T18:46:47.412000Z","last_modified_at":null,"cvss_v3_score":9.4,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:H","cvss_v3_severity":"CRITICAL","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-287"],"nvd_references":["https://github.com/WWBN/AVideo/security/advisories/GHSA-9hv9-gvwm-95f2","https://github.com/WWBN/AVideo/commit/388fcd57dbd16f6cb3ebcdf1d08cf2b929941128"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:29:55.288052Z"},"effective_severity":"CRITICAL","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"L","value_label":"Low"},{"metric":"I","name":"Integrity","value":"H","value_label":"High"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"wwbn","vendor_name":"WWBN","product_slug":"avideo","product_name":"AVideo","version_start":"<= 26.0","version_start_inclusive":true,"version_end":"<= 26.0","version_end_inclusive":true,"cpe23_uri":"cve5:wwbn:avideo:<= 26.0:<= 26.0"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-9hv9-gvwm-95f2","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/WWBN/AVideo/commit/388fcd57dbd16f6cb3ebcdf1d08cf2b929941128","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-03-23T18:46:47.412000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:53:20.032350Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:53:20.032350Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:53:20.032350Z","label":"CVSS score revised","source":"cvelistv5"}]}
