CVE-2025-31497 — TEIGarage is a webservice and RESTful service to transform, convert and validate various formats, focussing on the TEI format

High CVSS 7.5

TEIGarage is a webservice and RESTful service to transform, convert and validate various formats, focussing on the TEI format. The Document Conversion Service contains a critical XML External Entity (XXE) Injection vulnerability in its document conversion functionality. The service processes XML files during the conversion process but fails to disable external entity processing, allowing an attacker to read arbitrary files from the server's filesystem. This vulnerability could allow attackers to read sensitive files from the server's filesystem, potentially exposing configuration files, credentials, or other confidential information. Additionally, depending on the server configuration, this could potentially be used to perform server-side request forgery (SSRF) attacks by making the server connect to internal services. This issue is patched in version 1.2.4. A workaround for this vulnerability includes disabling external entity processing in the XML parser by setting the appropriate security features (e.g., XMLConstants.FEATURE_SECURE_PROCESSING).

Matched remediation archetype

XML external entity and unsafe XML processing

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Inventory XML parsers used by APIs, file imports, office or image formats, identity protocols, feeds, and background jobs.
  • Determine whether document type declarations, external entities, XInclude, schemas, or network resolvers are enabled.
  • Map parser filesystem and network access and the sensitivity of documents it processes.

Remediate safely

  • Configure each parser to reject document type declarations and disable external entity, XInclude, and network resolution features.
  • Prefer a data format or hardened parser that does not support external resolution, and apply input size and depth limits.
  • Update affected XML libraries and centralize secure parser construction so callers cannot silently override it.
