{"id":"CVE-2026-43881","summary":"WWBN AVideo: Unauthenticated User Enumeration in `objects/users.json.php` via `isCompany` Parameter Flips `$ignoreAdmin = true` and Defeats Admin-Only Listing Guard","details":"WWBN AVideo is an open source video platform. In versions up to and including 29.0, objects/users.json.php exposes two unauthenticated paths that disclose the full set of registered user accounts. The isCompany request parameter causes the handler to set $ignoreAdmin = true for any non-admin caller (including unauthenticated visitors), which defeats the admin-only guard inside User::getAllUsers()/User::getTotalUsers(). A second path accepts users_id and calls User::getUserFromID() directly with no permission check, producing a single-user oracle. Both paths return id, identification (display name), channel URL, photo, background, and status, plus the total account count. Commit d9cdc702481a626b15f814f6093f1e2a9c20d375 contains an updated fix.","aliases":["GHSA-6rvw-7p8v-mjfq"],"modified":"2026-08-12T03:51:26.602844040Z","published":"2026-05-11T20:38:06.930Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-306"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43881.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43881.json"},{"type":"ADVISORY","url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-6rvw-7p8v-mjfq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43881"},{"type":"FIX","url":"https://github.com/WWBN/AVideo/commit/d9cdc702481a626b15f814f6093f1e2a9c20d375"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wwbn/avideo","events":[{"introduced":"0"},{"fixed":"d9cdc702481a626b15f814f6093f1e2a9c20d375"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"29.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["29.0","26.0","25.0","24.0","22.0","21.0","18.0","14.3.1","14.3","12.4","11.6","11.5","11.1.1","11.1","11","10.8","8.9.1","8.9","8.7","8.6","8.5","8.1","7.8","7.7","7.6","7.4","7.3","7.2","4.0","3.4","2.7","2.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43881.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"}]}
