CVE-2026-47694 is a medium-severity cross-site scripting vulnerability in Wwbn Avideo, published on 29 May 2026. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Official description
WWBN AVideo is an open source video platform. In 29.0 and earlier, AVideo stores category descriptions from user input and later renders category_description as raw HTML in the Gallery view. A user who can create or edit categories can store JavaScript in a category description, which executes when another user views the affected Gallery/category page.
