Description
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 a mismatch between the parameter read during authorization (body `ids`) and the parameter read during execution (URL `id`), allowing a body-supplied `ids` value to satisfy the ownership check while the handler operated on a different, attacker-chosen resource. This makes it possible for authenticated attackers, with contributor-level access and above, to modify, delete, or take ownership of arbitrary events belonging to other users by supplying their own resource ID in the request body while targeting a victim's resource ID in the URL path.
