2DescriptionCVE.org
The Greenshift - animation and page builder blocks plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the _gspb_post_css post meta value and the dynamicAttributes block attribute in all versions up to, and including, 12.8.5 due to insufficient input sanitization and output escaping.
