{"id":"CVE-2026-107627","kind":"vulnerability","aliases":["CVE-2026-107627"],"related":[],"title":"Greenshift WordPress plugin: stored XSS through comment parameter","description":"The Greenshift – animation and page builder blocks plugin for WordPress is vulnerable to Stored DOM-Based Cross-Site Scripting via the 'comment' parameter in all versions up to, and including, 13.2.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires an administrator to have published a page containing a Text Animated block with Content set to Blocks, a Latest Comments block with excerpts enabled nested inside it, and at least one Animated Texts value configured — conditions that cause the gs-textanimate script to be enqueued and process the comment excerpts.","summary":"The Greenshift animation and page builder plugin for WordPress fails to sanitize the 'comment' parameter, letting unauthenticated attackers store script that runs in pages.
