CVE-2026-33295: Wwbn avideo cross-site scripting vulnerability

Wwbn · Avideo

WWBN AVideo is an open source video platform. Prior to version 26.0, WWBN/AVideo contains a stored cross-site scripting vulnerability in the CDN plugin's download buttons component. The `clean_title` field of a video record is interpolated directly into a JavaScript string literal without any escaping, allowing an attacker who can create or modify a video to inject arbitrary JavaScript that executes in the browser of any user who visits the affected download page. Version 26.0 fixes the issue.
