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.
