Wishlist Member <= 3.30.1 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Plugin Options Update via 'wishlistmember_team_accounts_save_settings' AJAX action

Title source: cna
STIX 2.1

Description

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 in all versions up to, and including, 3.30.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update arbitrary plugin options, includes the REST API Secret Key, which can be used to create a new membership level assigned the administrator WordPress role, and register an arbitrary administrator-level user account, resulting in complete site takeover.
