WPO365 | Login Plugin (<= 43.2)

A Cross-Site Request Forgery (CSRF) vulnerability in the WPO365 | Login plugin for WordPress, affecting versions up to and including 43.2, allows unauthenticated attackers to overwrite arbitrary plugin options. This is due to a misconfiguration where the nonce check is effectively disabled. By tricking a site administrator into clicking a malicious link, an attacker can manipulate settings such as enabling the SCIM REST endpoint, planting a SCIM secret token, and setting the default user role for new registrations to 'administrator', potentially leading to full site compromise and unauthorized administrative access.
