 "title": "Easy Optimizer <= 2.7.5 - Unauthenticated Sensitive Information Exposure via Forged 'easyopt_user_role' Cookie",
 "description": "The Easy Optimizer plugin for WordPress is vulnerable to Sensitive Information Exposure via the page cache drop-in (advanced-cache.php) in all versions up to, and including, 2.7.5, due to the drop-in treating any request with a cookie whose name starts with 'wordpress_logged_in_' as logged in and then picking which logged-in cached copy to serve from the unsigned, client-controlled 'easyopt_user_role' cookie. This makes it possible for unauthenticated attackers to send a cookie with that name and any value, set 'easyopt_user_role' to another role (such as administrator) or per-user tag, and receive the page copy cached for that role or user, exposing content meant only for those users. Exploitation requires the non-default 'Cache for logged-in users' setting to be enabled.",
