veraPDF validation model is an implementation of the veraPDF validation model. From 1.25.73 until 1.30.2 and 1.31.71, veraPDF-validation contains an XML External Entity vulnerability in PDFAValidator.validate(…) and GFPDAcroForm.getdynamicRender(), where default DocumentBuilderFactory parsing of rich-text annotation or form-field values and XFA configurations in untrusted PDFs can allow local file disclosure and outbound network requests. This issue is fixed in versions 1.30.2 and 1.31.71.
Weakness
The product processes an XML document that can contain XML entities with URIs that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output.
