From 1.17.35 until 1.30.2 and 1.31.71, veraPDF-validation contains an XML External Entity (XXE) vulnerability in validation-model/src/main/java/org/verapdf/gf/model/impl/pd/GFPDAcroForm.java in the getdynamicRender() method, where a crafted PDF containing a malicious XFA stream can cause external entity expansion during PDF/UA-1 validation and allow local file disclosure or outbound server-side requests. This issue is fixed in versions 1.30.2 and 1.31.71."
