CVE-2026-33238

EUVD-2026-13891

WWBN AVideo is an open source video platform. Prior to version 26.0, the `listFiles.json.php` endpoint accepts a `path` POST parameter and passes it directly to `glob()` without restricting the path to an allowed base directory. An authenticated uploader can traverse the entire server filesystem by supplying arbitrary absolute paths, enumerating `.mp4` filenames and their full absolute filesystem paths wherever they exist on the server — including locations outside the web root, such as private or premium media directories. Version 26.0 contains a patch for the issue.

Common Weakness Enumeration

CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
The software uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the software does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
