Greenshift WordPress plugin vulnerabilities

The Greenshift – animation and page builder blocks plugin for WordPress (versions up to and including 13.2.0) is vulnerable to Reflected Cross-Site Scripting via the '{{GET:}}' Dynamic Placeholder. Due to insufficient input sanitization and output escaping, an unauthenticated attacker can inject arbitrary scripts that execute when a user is tricked into clicking a crafted link.

The Greenshift WordPress plugin before version 13.2.0 does not properly escape a block animation attribute before outputting it within an HTML attribute, allowing users with contributor-level access and above to inject arbitrary web scripts that execute when the content is viewed.

The Greenshift WordPress plugin before version 13.2.0 does not validate a user-supplied URL before fetching it server-side, allowing users with contributor-level access and above to make the server issue requests to arbitrary hosts and read the response.
