Technical details

The WishList Member plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'WishListMember\Features\Team_Accounts::save_settings' function. This vulnerability affects all versions up to and including 3.30.1. An authenticated attacker with Subscriber-level permissions or higher can exploit this flaw to update arbitrary plugin options. Specifically, an attacker can modify the REST API Secret Key to create a new membership level with the WordPress 'administrator' role and register a new admin user. This results in a full privilege escalation and complete site takeover. The attack is reachable over the network and requires only low-level authenticated access.
