Description

The Eventin plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 4.0.34. This is due to the plugin not properly validating a user's identity or capability prior to updating their details like email in the 'Eventin\Speaker\Api\SpeakerController::update_item' function. This makes it possible for unauthenticated attackers with contributor-level and above permissions to change arbitrary user's email addresses, including administrators, and leverage that to reset the user's password and gain access to their account.

• CWE-639Authorization Bypass Through User-Controlled KeyThe system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.
