{"id":"CVE-2026-34364","summary":"AVideo has User Group-Based Category Access Control Bypass via Missing and Broken Group Filtering in categories.json.php","details":"WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `categories.json.php` endpoint, which serves the category listing API, fails to enforce user group-based access controls on categories. In the default request path (no `?user=` parameter), user group filtering is entirely skipped, exposing all non-private categories including those restricted to specific user groups. When the `?user=` parameter is supplied, a type confusion bug causes the filter to use the admin user's (user_id=1) group memberships instead of the current user's, rendering the filter ineffective. Commit 6e8a673eed07be5628d0b60fbfabd171f3ce74c9 contains a fix.","aliases":["GHSA-73gr-r64q-7jh4"],"modified":"2026-08-12T03:51:22.019575332Z","published":"2026-03-27T18:11:05.866Z","database_specific":{"cwe_ids":["CWE-863"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/34xxx/CVE-2026-34364.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/34xxx/CVE-2026-34364.json"},{"type":"ADVISORY","url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-73gr-r64q-7jh4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34364"},{"type":"FIX","url":"https://github.com/WWBN/AVideo/commit/6e8a673eed07be5628d0b60fbfabd171f3ce74c9"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wwbn/avideo","events":[{"introduced":"0"},{"fixed":"6e8a673eed07be5628d0b60fbfabd171f3ce74c9"}],"database_specific":{"cpe":"cpe:2.3:a:wwbn:avideo:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"last_affected":"26.0"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["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-2026-34364.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"}]}
