Description
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. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
