What the vulnerability does
The Tiare Membership plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.2. This is due to the 'tiare_membership_init_rest_api_register' function not restricting what user roles a user can register with. This makes it possible for unauthenticated attackers to supply the 'administrator' role during registration and gain administrator access to the site.
Explanation of Vulnerability in Simple Terms
Tiare Membership versions 1.2 and earlier contain a privilege management flaw that allows unauthenticated attackers to gain full control over the application. An attacker can read, modify, or delete any data and disrupt service without needing credentials or user interaction. This affects all installations running the vulnerable version.
What an attacker can do
Read, modify, or delete any data in the application and disrupt service without authentication.
Potential impact on your site
Complete compromise of the membership system, including user data exposure, unauthorized access, and potential service downtime.
Conditions required to exploit
Network access to the application. No authentication or user interaction required.
