Authenticated file theft and deletion via unrestricted fileURI
Published Mar 23, 2026 · Updated Mar 23, 2026
Path traversal in World Wide Broadcast Network AVideo 26.0 and earlier allows remote authenticated users to read or delete server files. The objects/import.json.php endpoint checks only that fileURI ends in .mp4, then copies that path, reads adjacent text or HTML files, and optionally unlinks them without restricting resolution to the videos directory. Upload permission is required; private videos can be imported into the attacker's account, while deletion is limited to files writable by the web server.
