The Groundhogg plugin for WordPress is vulnerable to Stored Cross-Site Scripting through the 'gh_form' shortcode in versions up to and including 2.7.9.8. The vulnerability arises from insufficient input sanitization and output escaping for attributes provided by users. This flaw enables authenticated attackers with contributor-level permissions and higher to inject arbitrary scripts into web pages.
