Description

The FleekDash V2 plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.6.2.2. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to overwrite the email address and password of any WordPress user, including administrators, enabling full account takeover and complete site compromise. The public /wp-json/fleekdash/v1/register endpoint auto-provisions a Subscriber-role account and returns a valid REST nonce regardless of the site's users_can_register setting, enabling unauthenticated attackers to self-provision the required credentials and nonce in a single prior request.
