Exploitation Summary

EIP tracks 1 public exploit for CVE-2026-14364. PoCs published by exploitintel.

AI-analyzed exploit summary This repository contains a functional exploit for CVE-2026-14364, a critical unauthenticated arbitrary password reset vulnerability in the TrueBooker WordPress plugin (versions ≤1.2.3). The exploit leverages a missing authorization check in the `user_front_resetpass` AJAX action, allowing attackers to reset passwords for any user (including administrators) by manipulating the `tbab-userid` parameter and bypassing activation key validation when the target's `user_activation_key` is empty.

Description

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.
