CVE-2025-31497Public exploitNetwork attack vector

Unauthenticated file disclosure via external XML entities

Published Apr 15, 2025 · Updated Apr 15, 2025

XXE injection in Text Encoding Initiative Consortium TEIGarage before 1.2.4 allows remote attackers to read server files via XML uploads. The Document Conversion Service parses attacker-supplied TEI XML with external entity resolution enabled and returns referenced file contents in conversion output. No authentication or user interaction is required; exposure is limited to files readable by the service account, with SSRF dependent on server configuration.
