{"id":"CVE-2026-33507","summary":"AVideo Affected by CSRF on Plugin Import Endpoint Enables Unauthenticated Remote Code Execution via Malicious Plugin Upload","details":"WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `objects/pluginImport.json.php` endpoint allows admin users to upload and install plugin ZIP files containing executable PHP code, but lacks any CSRF protection. Combined with the application explicitly setting `session.cookie_samesite = 'None'` for HTTPS connections, an unauthenticated attacker can craft a page that, when visited by an authenticated admin, silently uploads a malicious plugin containing a PHP webshell, achieving Remote Code Execution on the server. Commit d1bc1695edd9ad4468a48cea0df6cd943a2635f3 contains a patch.","aliases":["GHSA-hv36-p4w4-6vmj"],"modified":"2026-04-10T05:42:49.347647Z","published":"2026-03-23T16:32:28.925Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33507.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-352"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33507.json"},{"type":"FIX","url":"https://github.com/WWBN/AVideo/commit/d1bc1695edd9ad4468a48cea0df6cd943a2635f3"},{"type":"ADVISORY","url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-hv36-p4w4-6vmj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33507"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wwbn/avideo","events":[{"introduced":"0"},{"last_affected":"aee1e11ee8d9343f87b7643e49cc32924b07979b"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"26.0"}]}}],"versions":["10.8","11","11.1","11.1.1","11.5","11.6","12.4","14.3","14.3.1","18.0","2.2","2.7","21.0","22.0","24.0","25.0","26.0","3.4","4.0","7.2","7.3","7.4","7.6","7.7","7.8","8.1","8.5","8.6","8.7","8.9","8.9.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-33507.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
