CVE-2026-14356: Missing authorization vulnerability

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.
