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.
CVE-2026-33238
This medium-severity CVE scores 4.3 under NVD CVSS v3. EPSS exploit probability: 0.0%, top 95% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- Lower severity and no public exploit yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
