# CVE-2026-14250: Themehunk Login Registration \<= 1.0.2 - Unauthenticated Privilege Escalation via 'role' Parameter

- Severity: CVSS 6.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2026-07-08 · Updated: 2026-07-08

## Affected

- themehunk TH Login Registration: through 1.0.2

## 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.
