CVE-2026-14364 in TrueBooker Plugin
Summary
by MITRE • 08/07/2026
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.

The TrueBooker plugin for WordPress presents a critical account takeover vulnerability that stems from inadequate password reset validation mechanisms. This flaw affects all versions up to and including 1.2.3, creating a significant security risk for WordPress installations that utilize this booking and scheduler system. The vulnerability operates by allowing unauthenticated attackers to initiate password reset requests for any user account without proper verification of the requester's identity, effectively bypassing the intended security controls designed to protect user credentials.
The technical implementation of this vulnerability resides in the plugin's failure to properly validate user identities during the password reset process. When a user requests a password reset, the system should verify that the request originates from the legitimate account owner through multiple authentication factors such as email verification tokens, session validation, or other cryptographic proofs of ownership. However, the TrueBooker plugin lacks these essential validation steps, enabling attackers to manipulate the password reset workflow and obtain reset tokens for arbitrary accounts without possessing legitimate access credentials.
This vulnerability creates substantial operational impact by providing attackers with the capability to compromise administrator accounts and gain full administrative control over affected WordPress installations. The implications extend beyond simple credential theft since administrators possess elevated privileges that allow them to modify website content, install malicious plugins, alter user permissions, and potentially use the compromised system as a foothold for further attacks within the network infrastructure. The vulnerability's exploitability is particularly concerning because it requires no prior authentication or privileged access to target any user account on the system.
From a cybersecurity perspective, this vulnerability aligns with CWE-613 which addresses insufficient session validation and improper authentication mechanisms in web applications. The flaw also maps to ATT&CK technique T1078 which covers legitimate credentials usage, as attackers can leverage compromised accounts to maintain persistent access. Organizations should prioritize immediate remediation by updating to the latest plugin version or implementing temporary workarounds such as disabling password reset functionality until a proper patch is applied. Additionally, security teams should monitor for suspicious account activity and consider implementing additional authentication layers including multi-factor authentication to reduce the risk of successful exploitation.
The vulnerability demonstrates the critical importance of proper input validation and authentication controls in web application development, particularly for plugins that handle sensitive user data and administrative functions. Organizations should conduct comprehensive security assessments of all installed plugins and themes to identify similar weaknesses that could potentially be exploited by threat actors. Regular security updates and patch management procedures become essential defenses against such vulnerabilities, as the rapid evolution of attack techniques requires constant vigilance in maintaining secure software environments.
