WWBN AVideo Affected by CSRF on Player Skin Configuration via admin/playerUpdate.json.php

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.

Weakness class (CWE)

Root cause

State-changing requests rely on the session cookie the browser sends automatically; nothing verifies that the request came from the user’s own page.
