## Description

The Greenshift – animation and page builder blocks plugin for WordPress is vulnerable to Stored DOM-Based Cross-Site Scripting via the Counter block prefix and postfix (data-prefix / data-postfix) and the Typewriter text animation (data-type) in all versions up to, and including, 13.2.2, due to the front-end scripts writing these values into the page with innerHTML instead of as text. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts that run whenever a user opens an injected page. The same sink is reached when an Interaction Layer copies attacker-supplied page data onto a Counter prefix.
