CVE-2026-33238: AVideo has a Path Traversal in listFiles.json.php that Enables Server Filesystem Enumeration

Noroxi assessment

Priority: Monitor (action score 17/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.43% (FIRST EPSS).
Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
Fixed version: wwbn/avideo (Packagist) 26.0.

Low priority for now. Upgrade to wwbn/avideo (Packagist) 26.0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.

Root cause

A user-supplied file name is joined with the allowed directory, but the result is never checked to confirm it is still inside that directory.
