The Better Messages – Chat Rooms, Group Chat, Private Messages & AI Chat Bots plugin for WordPress is vulnerable to generic SQL Injection via 'group_id' Message Meta Parameter in all versions up to, and including, 3.0.4 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. Exploitation requires the BuddyBoss Platform plugin to be installed with its Social Groups component disabled, a state that persists on any site that has previously toggled the Groups component off since BuddyBoss does not drop the wp_bp_groups table upon deactivation.
