CVE-2026-16142

TrueBooker <= 1.2.6 - Unauthenticated Account Takeover via Insecure Direct Object Reference in 'truebooker_wp_user_id' Parameter

TrueBooker <= 1.2.6 - Unauthenticated Account Takeover via Insecure Direct Object Reference in 'truebooker_wp_user_id' Parameter

The TrueBooker plugin for WordPress is vulnerable to Account Takeover in all versions up to, and including, 1.2.6. This is due to the add_front_user_update() AJAX handler being registered for unauthenticated users and accepting an arbitrary truebooker_wp_user_id value, which is passed directly to wp_update_user() without verifying authentication or ownership. This makes it possible for unauthenticated attackers to change any WordPress user account email address, including an administrator, by submitting the target user ID and an attacker-controlled email address. An attacker can then use the native WordPress password reset flow to receive the reset link at the attacker-controlled email address and take over the account.
