CVE-2026-105086: WWBN AVideo stored XSS in video titles via double encoding

CVE-2026-105086 · Severity: high · CVSS 8.7 · Published 2026-10-04

WWBN AVideo is a video hosting and streaming platform. Authenticated users who can upload videos can inject malicious JavaScript code by submitting specially crafted titles that bypass security filters. When other users view trending videos, video galleries, embedded videos, or playlists, the injected code executes in their browsers, potentially allowing attackers to steal sessions, redirect users, or perform actions on their behalf.

Technical details

The safeString() function strips HTML tags before decoding HTML entities, but the function is called twice during video save (in setTitle() and save()), allowing double-encoded entities like "&&lt;" to bypass the first pass and become executable tags after the second pass. An authenticated attacker can inject HTML/JavaScript via the video title parameter in videoAddNew.json.php; the payload is stored unescaped and echoed without escaping in trending.php, videoEmbeded.php, YouPHPFlix2 gallery rows, and playlist.php, executing in visitors' browsers without Content-Security-Policy protection.
