Descriptions

Cross-Site Request Forgery (CSRF) vulnerability in WP Engine PHP Compatibility Checker plugin <= 1.5.2 versions.

The PHP Compatibility Checker plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.5.2. This is due to missing or incorrect nonce validation on the start_test and cleanup function. This makes it possible for unauthenticated attackers to start a new compatibility scan or delete scan results via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
