CVE-2026-3565

What is known

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.

Business impact

Successful exploitation of CVE-2026-3565, a medium vulnerability (CVSS 4.3) affecting the affected product, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.

Recommended administrator action

Confirm whether the affected product is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
