The Order Delivery Date WordPress plugin before 12.3.1 does not have authorization and CSRF checks when importing settings. Furthermore it also lacks proper checks to only update options relevant to the Order Delivery Date WordPress plugin before 12.3.1. This leads to attackers being able to modify the default_user_role to administrator and users_can_register, allowing them to register as an administrator of the site for complete site takeover.
The plugin settings import endpoint does not require authentication or check CSRF tokens, allowing any user — including unauthenticated ones — to send a crafted HTTP request. Additionally, the lack of filtering on updated options allows modification of any WordPress parameters beyond the plugin's scope. An attacker can set the 'default_user_role' option to 'administrator' and enable 'users_can_register', which allows them to register an account with site administrator privileges.
An attacker can obtain full WordPress administrator privileges, leading to complete site takeover — including installation of malicious software, theft of user data, and modification or deletion of website content.
The Order Delivery Date for WordPress plugin must be immediately updated to version 12.3.1 or newer. It is also recommended to check the list of website users for unauthorized administrator accounts and reset the 'default_user_role' and 'users_can_register' options to secure values.
