Description
The Greenshift – animation and page builder blocks plugin for WordPress is vulnerable to Sensitive Information Exposure via the {{COOKIE:...}} dynamic placeholder in all versions up to, and including, 13.2.2, due to the placeholder printing any cookie, including WordPress authentication, logged-in, session and post password cookies, into block markup such as element src/href or dynamic attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to make a higher-privileged user who views or previews their post send that user's HttpOnly login cookie to an attacker-controlled host, which can lead to session hijacking.
