CVE-2026-86725Public exploitNetwork attack vector

Cross-account OAuth token overwrite via unchecked row ID

Published Sep 8, 2026 · Updated Sep 8, 2026

Missing authorization in WWBN AVideo's SocialMediaPublisher plugin allows remote authenticated users to overwrite other users' OAuth tokens. Publisher_user_preferences/add.json.php loads an attacker-supplied row ID, reassigns the row to the session user, replaces its JSON token data, and saves it without checking ownership. Any registered account can enumerate sequential row IDs; a successful request transfers ownership and permits deletion, severing the victim's provider linkage.
