Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

veraPDF-validation versions 1.17.35 up to 1.30.2 and 1.31.1 up to 1.31.71 (Maven org.verapdf:validation-model and validation-model-jakarta) are affected. An attacker who supplies a crafted PDF to an application that validates it with the PDFAValidator.validate or GFPDAcroForm getdynamicRender APIs can cause external XML entities to be expanded during parsing, potentially disclosing local files and making outbound network requests. Upgrade to version 1.30.2 or 1.31.71.
