Detailsinfo

A vulnerability classified as critical has been found in themetechmount TrueBooker Plugin up to 1.2.6. Affected is the function add_front_user_update of the component AJAX Handler. The manipulation of the argument truebooker_wp_user_id with an unknown input leads to a password recovery vulnerability. CWE is classifying the issue as CWE-640. The product contains a mechanism for users to recover or change their passwords without knowing the original password, but the mechanism is weak. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.
