CVE-2026-54078Network attack vector

Arbitrary file read via unsafe rich-text parsing

Published Jul 29, 2026 · Updated Jul 29, 2026

XXE in veraPDF-validation 1.25.73 through 1.30.1 and 1.31.1 through 1.31.70 allows remote attackers to read local files via crafted PDFs. DictionaryKeysHelper.getRichTextStringOrStreamEntryStringRepresentation parses rich-text /RC or /RV data with a default DocumentBuilderFactory that resolves external entities, then concatenates expanded text into the validation report. Exploitation requires validation of an attacker-supplied PDF and exposes server files or enables server-side requests without authentication.
