What is CVE-2026-14250?
CVE-2026-14250 is a medium-severity vulnerability in themehunk TH Login Registration, published on 8 Jul 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
The Themehunk Login Registration plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 1.0.2. This is due to the handle_frontend_register() function in the unauthenticated /thlogin/v1/register REST endpoint accepting a user-controlled 'role' parameter and validating it only against get_editable_roles() — which returns every defined editable site role, including 'editor' — before passing it to wp_insert_user(). This makes it possible for unauthenticated attackers, when public user registration is enabled, to create new accounts with the editor role.
Weakness: CWE-269
