CVE-2026-54082: veraPDF-validatio: Use of Default `DocumentBuilderFactory` leads to XXE When Processing Untrusted PDFs
veraPDF-validation has an XML External Entity (XXE) vulnerability in two PDF parsing paths (validate and GFPDAcroForm.getdynamicRender()). A malicious/crafted PDF supplied to a veraPDF consumer can lead to the expansion of external entities while parsing rich-text annotation/form-field values or XFA configurations, allowing local file disclosure and potentially outbound network requests depending on the runtime (host) environment.
