EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.7 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 76% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

veraPDF validation provides PDF/A and PDF/UA validation, feature reporting, and metadata repair. 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.
