Cross-Site Scripting (XSS) in WWBN AVideo (CVE-2026-39367)
Summary
Cross-site scripting in WWBN AVideo (CVE-2026-39367). Risk of unauthorized operations or information disclosure.
Original description
The description as published by the source.
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 elements contain JavaScript. This payload executes in the browser of any unauthenticated visitor to the public EPG page, enabling session hijacking and account takeover.
