Input validation vulnerability in Greenshift – animation and page builder blocks 11.5.5

The Greenshift plugin for WordPress has a security issue that makes it vulnerable to an attack called Stored Cross-Site Scripting. This can happen in versions 11.5.5 and below because the plugin does not properly clean up the information it receives from users and may not protect against malicious code being added to pages. This means that someone with contributor-level access or higher can add harmful web scripts to a page, which will run whenever someone visits that page.
