Technical details

A stored cross-site scripting (XSS) vulnerability exists in Ninja Forms 3.15.3 where non-RTE textarea fields fail to HTML-encode submitted values before rendering them in the legacy submission editor. An unauthenticated attacker can inject JavaScript that breaks out of the textarea element; when an authenticated WordPress administrator opens the attacker-controlled submission URL, the payload executes in the WordPress admin context.
