Description

A stored cross-site scripting (XSS) vulnerability exists in pdfonline.foxit.com within the Layer Import functionality. A crafted payload can be injected into the “Create new Layer” field during layer import and is later rendered into the DOM without proper sanitization. As a result, the injected script executes when the Layers panel is accessed.
