At a glance

CVE-2026-0920 is a critical-severity Improper Privilege Management vulnerability in the LA-Studio Element Kit for Elementor WordPress plugin, affecting versions <= 1.5.6.3. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 1.6.0; sites on affected versions should update now. Disclosed January 2026, reported by Athiwat Tiprasaharn (Jitlada).

Vulnerability Overview

The LA-Studio Element Kit for Elementor plugin for WordPress is vulnerable to Administrative User Creation in all versions up to, and including, 1.5.6.3. This is due to the 'ajax_register_handle' function not restricting what user roles a user can register with. This makes it possible for unauthenticated attackers to supply the 'lakit_bkrole' parameter during registration and gain administrator access to the site.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-269: Improper Privilege Management

LA-Studio Element Kit for Elementor <= 1.5.6.3 carries this weakness at ajax_register_handle, and reaching it takes no account at all. Improper privilege management means the code lets an account end up with capabilities its role should not have.

It converts a low-privileged account into an administrative one, which makes every other restriction on the site irrelevant. For LA-Studio Element Kit for Elementor the fix is 1.6.0: builds <= 1.5.6.3 are affected, anything from 1.6.0 onward is not.

Remediation

Update to version 1.6.0, or a newer patched version

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: LA-Studio Element Kit for Elementor 1.6.0 closes this, and updating the plugin is the step that ends it.
