Associated Vulnerability

Title: GP Premium <= 2.4.0 - Reflected Cross-Site Scripting (CVE-2024-3469)
Description:The GP Premium plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the message parameter in all versions up to, and including, 2.4.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

Description

The GP Premium plugin for WordPress up to 2.4.0 is vulnerable to reflected XSS via the 'message' parameter in inc/verify.php (lines 95-101), where a message passed with sl_activation=false is URL-decoded and used unsanitized in add_settings_error(), allowing XSS payloads to be reflected in admin notices.
