WordPress Plugin Vulnerabilities

MC4WP: Mailchimp for WordPress < 4.8.5 - Unauthorised Actions via CSRF

Description

The plugin did not properly check for CSRF in some of its actions handled by the listen_for_actions method (hooked as admin_init), allowing attackers to make logged in users with the manage_options capability do unwanted actions such as empty the logs, dismiss notice and so on
