CVE-2026-50183— WWBN AVideo 跨站脚本漏洞

WWBN AVideo: Stored XSS via Hostile YouTube Video Title in AVideo YouTubeAPI Gallery Section

WWBN AVideo is an open source video platform. Versions 29.0 and below contain a stored Cross-Site Scripting vulnerability in the YouTubeAPI plugin. The 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. When the visitor is an AVideo administrator, the injected JavaScript performs any admin action (create user, promote to admin, change configuration, install plugin) that uses cookie-based authentication without an additional CSRF token, escalating the bug into full administrative takeover. The payload persists for the duration of cacheTimeout (default 3600 seconds) after the malicious title is set on YouTube and survives YouTube removing the hostile video for the same window. This issue has been addressed by commit https://github.com/WWBN/AVideo/commit/7292129eaee5f609beae103b5cb387d55f17b877.
