Does this matter?

Lower severity and a low EPSS score (0.19%). Track it; it rarely justifies an emergency change on its own.

Description

WWBN AVideo is an open source video platform. In versions 26.0 and prior, AVideo's EPG (Electronic Program Guide) feature parses XML from user-controlled URLs and renders programme titles directly into HTML without any sanitization or escaping. A user with upload permission can set a video's epg_link to a malicious XML file whose <title> elements contain JavaScript. This payload executes in the browser of any unauthenticated visitor to the public EPG page, enabling session hijacking and account takeover.
