CVE-2026-33493
No affected components available
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the objects/import.json.php endpoint accepts a user-controlled fileURI POST parameter with only a regex check that the value ends in .mp4. Unlike objects/listFiles.json.php, which was hardened with a realpath() + directory prefix check to restrict paths to the videos/ directory, import.json.php performs no directory restriction. This allows an authenticated user with upload permission to: (1) steal any other user's private video files by importing them into their own account, (2) read .txt/.html/.htm files adjacent to any .mp4 file on the filesystem, and (3) delete .mp4 and adjacent text files if writable by the web server process. Commit e110ff542acdd7e3b81bdd02b8402b9f6a61ad78 contains a patch.
