The record
A stored cross-site scripting (XSS) vulnerability exists in pdfonline.foxit.com within the Page Templates feature. A crafted payload can be stored as the template name, which is later rendered into the DOM without proper sanitization. As a result, the injected script executes each time the affected PDF is loaded.
