CVE-2026-118201 is a medium-severity Improper Authentication vulnerability in the Limit Login Attempts Security WordPress plugin, affecting versions 3.0.0 – 3.4.0. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). The issue is fixed in version 3.4.1; sites on affected versions should update now. Disclosed November 2026, reported by Qi Qin.
Vulnerability Overview
The Limit Login Attempts Reloaded plugin for WordPress is vulnerable to Two-Factor Authentication Bypass in versions 3.0.0 through 3.4.0. This is due to failure to apply two-factor authentication enforcement consistently across all available password-based login routes. This makes it possible for unauthenticated attackers to authenticate by exploiting an unprotected login route, fully bypassing the two-factor authentication requirement and gaining access to the account. Two-factor authentication must be enabled on the targeted account, and the attacker must already know that account's password.
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 interaction from a victim user.
CWE-287: Improper Authentication
Reaching this weakness in Limit Login Attempts Security 3.0.0 – 3.4.0 takes a caller who can reach the endpoint. Improper authentication means the mechanism that proves who a caller is can be satisfied without the secret it was supposed to require.
An attacker authenticates as another user — administrators included — without ever knowing a password, so password policies and login rate limits never come into play. For Limit Login Attempts Security the fix is 3.4.1: builds 3.0.0 – 3.4.0 are affected, anything from 3.4.1 onward is not.
Remediation
Update to version 3.4.1, or a newer patched version
How does WordSec protect against this?
Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Limit Login Attempts Security 3.4.1 closes this, and updating the plugin is the step that ends it.
