Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Since the plugin lacks proper CSRF token validation, attackers can craft malicious links that, when clicked by a logged-in admin, cause the browser to execute arbitrary JavaScript (Reflected XSS), potentially stealing session cookies or performing unauthorized actions.
