Description
pdfmake 0.3.8 before 0.3.12 fails to apply the setLocalAccessPolicy() restriction to images referenced inside SVG content, allowing attackers to read blocked local files. Attackers supplying a document definition can add an SVG image href pointing to a local path, embedding restricted file contents in the generated PDF.
