CVE-2026-50183: WWBN AVideo: Stored XSS via Hostile YouTube Video Title in AVideo YouTubeAPI Gallery Section

A stored Cross-Site Scripting vulnerability (CWE-79; chained CWE-829, Inclusion of Functionality from Untrusted Control Sphere) in the AVideo YouTubeAPI plugin renders the snippet.title field returned by the YouTube Data API into the homepage gallery markup with no HTML encoding. The title is set by the YouTube video uploader (anyone in the world) and is treated by AVideo as trusted content. A YouTube uploader who controls a video matching the operator’s configured query injects HTML into the AVideo homepage by setting their video’s title to a JavaScript-bearing string; the payload then executes in the browser of every visitor who loads any page that renders the gallery.
