CVE-2022-4466Public exploitNetwork attack vector

Stored script execution via unescaped shortcode attributes

Published Mar 13, 2023 · Updated Feb 27, 2025

Stored XSS in ConnektHQ Ajax Load More before 5.6.0.3 allows remote authenticated users to execute script through shortcode attributes. The shortcode renderer places attributes such as id and button labels into generated page markup without validating or escaping their HTML attribute context. Contributor-level access is sufficient to store a payload in a post; execution requires another user to view the rendered shortcode and exposes data and actions available to that user's browser session.
