CVE-2026-33681

Wwbn Avideo path traversal

7.2 HIGHPublic exploitEPSS 0.64%
  1. Published23 Mar 2026

Description

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `objects/pluginRunDatabaseScript.json.php` endpoint accepts a `name` parameter via POST and passes it to `Plugin::getDatabaseFileName()` without any path traversal sanitization. This allows an authenticated admin (or an attacker via CSRF) to traverse outside the plugin directory and execute the contents of any `install/install.sql` file on the filesystem as raw SQL queries against the application database. Commit 81b591c509835505cb9f298aa1162ac64c4152cb contains a patch.
