It fails to verify user permissions properly, allowing unauthenticated attackers to change email addresses of any user account, including administrators. This can lead to account takeover by resetting passwords.

Detection Guidance

To detect this vulnerability, check if the TrueBooker plugin version 1.2.3 or lower is installed on your WordPress site. Review user account email changes for unauthorized modifications, especially for admin accounts. Monitor logs for suspicious password reset requests.
