CVE-2024-6961: Guardrails AI vulnerable to Improper Restriction of XML External Entity Reference

RAIL documents are an XML-based format invented by Guardrails AI to enforce formatting checks on LLM outputs. Guardrails users that consume RAIL documents from external sources are vulnerable to XXE, which may cause leakage of internal file data via the SYSTEM entity.

Root Cause Analysis

The vulnerability stems from XML parsing without disabling external entity resolution. The commit diff shows both locations used ET.XMLParser without 'resolve_entities=False':

In constants_container.py, the fill_constants method reads external XML files
In rail_schema.py, rail_string_to_schema processes user-provided RAIL strings Both functions parse untrusted XML input and were patched by adding resolve_entities=False to their XML parsers, directly addressing the XXE vulnerability. The PoC demonstrates exploitation through RAIL document processing, confirming these are the entry points.
