Advisory
Source description from Wordfence Intelligence, credited to Muni Nitish Kumar Yaddala.
The Eventin plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 4.1.20. This is due to the permission check preferring the `ids` body parameter over the URL path `id`, allowing the check to pass against the attacker's own account while the deletion executed against the victim's account in the path. This makes it possible for authenticated attackers, with contributor-level access and above, to delete arbitrary speaker or organizer user accounts by supplying their own user ID in the request body `ids` parameter while targeting a victim's account ID in the URL path.
