At a glance

CVE-2026-18469 is a high-severity Improper Restriction of Excessive Authentication Attempts vulnerability in the Login & Register Customizer WordPress plugin, affecting versions <= 4.0.1. It carries a CVSS score of 8.1 (reachable over the network; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 4.0.2; sites on affected versions should update now. Disclosed August 2026, reported by Ryan Fabella.

Vulnerability Overview

The Login & Register Customizer – Forms, Popup, Profile & WooCommerce plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 4.0.1. This is due to the plugin not restricting the number of password reset code attempts. This makes it possible for unauthenticated attackers to change arbitrary user's passwords including administrators, and leverage that to gain access to their account.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, 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-307: Improper Restriction of Excessive Authentication Attempts

The product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame.

Remediation

Update to version 4.0.2, 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: Login & Register Customizer 4.0.2 closes this, and updating the plugin is the step that ends it.
