At a glance

CVE-2026-14364 is a critical-severity Weak Password Recovery Mechanism for Forgotten Password vulnerability in the TrueBooker WordPress plugin, affecting versions <= 1.2.3. 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 1.2.4; sites on affected versions should update now. Disclosed August 2026, reported by thevietronin.

Vulnerability Overview

The TrueBooker – Appointment Booking and Scheduler System plugin for WordPress is vulnerable to account takeover via improper password reset validation in all versions up to, and including, 1.2.3. This is due to the plugin not properly validating a user's identity before resetting their password. This makes it possible for unauthenticated attackers to reset the password of arbitrary user accounts, including administrators, and gain access to those accounts.

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-640: Weak Password Recovery Mechanism for Forgotten Password

Reaching this weakness in TrueBooker <= 1.2.3 takes no account at all. A weak password recovery mechanism means the path that lets someone back into an account without their password is easier to complete than the password itself.

An attacker takes over an account through the recovery flow without ever seeing the password, and on an administrator account that is full control of the site. For TrueBooker the fix is 1.2.4: builds <= 1.2.3 are affected, anything from 1.2.4 onward is not.

Remediation

Update to version 1.2.4, 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: TrueBooker 1.2.4 closes this, and updating the plugin is the step that ends it.
