Technical details

The WishList Member plugin for WordPress is vulnerable to an authorization bypass due to a missing capability check on the 'WishListMember3_Hooks::generate_api_key' function. This flaw exists in all versions up to and including 3.30.1. An authenticated attacker with Subscriber-level permissions or higher can trigger this function to update the REST API Secret Key. By manipulating this key, the attacker can create a new membership level with the WordPress 'administrator' role and register a new user account assigned to that level. This sequence of actions results in a complete privilege escalation and site takeover. The vulnerability is reachable via the network and requires only low-level authenticated access.
