## Technical details

The plugin does not correctly validate WordPress REST API nonces for cookie-authenticated requests when an attacker-controllable condition is present, resulting in a Cross-Site Request Forgery (CSRF) vulnerability. An unauthenticated attacker can craft a malicious page that, when visited by a logged-in administrator, performs administrator-only actions such as creating new admin accounts. The vulnerability affects versions before 1.8.2 and is fixed in 1.8.2.
