Title
veraPDF Validation XXE via Rich Text
Summary
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 (XXE) vulnerability in validation-model/src/main/java/org/verapdf/gf/model/tools/DictionaryKeysHelper.java in getRichTextStringOrStreamEntryStringRepresentation(), where a crafted PDF containing a malicious rich-text /RC or /RV entry can cause external entity expansion and reflect local file contents into the validation report. This issue is fixed in versions 1.30.2 and 1.31.71.
