{"id":"CVE-2026-35450","aliases":["GHSA-2vg4-rrx4-qcpq"],"url":"https://o3.security/vulnerability/CVE-2026-35450","summary":"WWBN AVideo has Unauthenticated FFmpeg Remote Server Status Disclosure via check.ffmpeg.json.php","details":"## Summary\n\nThe `plugin/API/check.ffmpeg.json.php` endpoint probes the FFmpeg remote server configuration and returns connectivity status without any authentication. All sibling FFmpeg management endpoints (`kill.ffmpeg.json.php`, `list.ffmpeg.json.php`, `ffmpeg.php`) require `User::isAdmin()`.\n\n## Details\n\nThe entire file at `plugin/API/check.ffmpeg.json.php`:\n\n```php\n<?php\n$configFile = __DIR__.'/../../videos/configuration.php';\nrequire_once $configFile;\nheader('Content-Type: application/json');\n\n$obj = testFFMPEGRemote();\n\ndie(json_encode($obj));\n```\n\nNo `User::isAdmin()`, `User::isLogged()`, or any access control check exists.\n\nCompare with sibling endpoints in the same directory:\n- `kill.ffmpeg.json.php` checks `User::isAdmin()`\n- `list.ffmpeg.json.php` checks `User::isAdmin()`\n\n## Proof of Concept\n\n```bash\ncurl \"https://your-avideo-instance.com/plugin/API/check.ffmpeg.json.php\"\n```\n\nReturns information about whether the platform uses a standalone FFmpeg server and its current reachability.\n\n## Impact\n\nInfrastructure reconnaissance revealing the encoding architecture. Limited direct impact but aids targeted attack planning.\n\n## Recommended Fix\n\nAdd an admin authentication check at `plugin/API/check.ffmpeg.json.php:3`, after `require_once $configFile;`:\n\n```php\nif (!User::isAdmin()) {\n    forbiddenPage('Admin only');\n}\n```\n\n---\n*Found by [aisafe.io](https://aisafe.io)*","published":"2026-04-06T21:46:54.779Z","modified":"2026-08-12T03:51:47.958153712Z","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"wwbn/avideo","fixedVersion":null}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35450.json"},{"type":"ADVISORY","url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-2vg4-rrx4-qcpq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35450"},{"type":"PACKAGE","url":"https://github.com/WWBN/AVideo"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:47.958153712Z"}}
