Summary

The Wishlist Member plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check in the 'WishListMember3_Hooks::generate_api_key' function in all versions up to and including 3.30.1. Authenticated attackers with Subscriber-level access or above can update the REST API Secret Key, which can be used to create a new membership level with the administrator WordPress role and register an arbitrary administrator-level user account, resulting in complete site takeover.

Risk Assessment

An attacker with low privileges can completely take over the WordPress site by creating an administrator account and gaining full control.

Recommendation

Update the Wishlist Member plugin to version 3.30.2 or later, which includes a capability check fix.
