What is CVE-2026-6897?

The Wishlist Member plugin for WordPress has a weakness that enables unauthorized data changes due to a lack of necessary capability checks in the 'WishListMember\Features\Team_Accounts::save_settings' function. This vulnerability affects all versions up to and including 3.30.1. Authenticated attackers with Subscriber-level access or higher can manipulate plugin settings, including the REST API Secret Key. This compromise allows them to create a new membership level with administrative rights and register new administrator accounts, leading to potential complete control over the affected WordPress site.

Affected Version(s)

Wishlist Member 0 <= 3.30.1
