What is CVE-2026-33493?

AVideo, an open source video platform developed by WWBN, has a vulnerability in its objects/import.json.php endpoint that allows authenticated users with upload permissions to exploit a lack of proper directory restrictions. This vulnerability permits an authenticated user to manipulate the fileURI POST parameter, which is limited to checking only for .mp4 file extensions. As a result, users can potentially steal private video files owned by other users, read adjacent .txt, .html, and .htm files from the filesystem, and even delete .mp4 files and any writable adjacent text files. A patch has been provided in commit e110ff542acdd7e3b81bdd02b8402b9f6a61ad78 to address these security concerns.
