{"id":"CVE-2026-39367","state":"PUBLISHED","title":"WWBN AVideo has Stored XSS via Malicious EPG XML Program Titles in AVideo EPG Page","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.
