Description
A stored cross-site scripting (XSS) vulnerability exists in the Portfolio feature of the Foxit PDF Editor cloud (pdfonline.foxit.com). User-supplied SVG files are not properly sanitized or validated before being inserted into the HTML structure. As a result, embedded HTML or JavaScript within a crafted SVG may execute whenever the Portfolio file list is rendered.
