The Greenshift – animation and page builder blocks plugin for WordPress is vulnerable to Stored DOM-Based Cross-Site Scripting via the 'url (comment_author_url)' parameter in all versions up to, and including, 13.2.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires the affected page to be configured with a GreenShift Interaction Layer attach-attribute action that copies a comment-author anchor's href into a Counter block's data-prefix or data-postfix attribute; given that configuration, the payload executes for every visitor who loads the Counter into the viewport once the comment is published.
