## Overview

A flaw was found in the file_type content detector of guardrails-detectors. This vulnerability allows a remote attacker to supply an arbitrary XML Schema Definition (XSD) string, which is processed without proper restrictions. This can lead to server-side requests to arbitrary URLs or local file reads, potentially resulting in sensitive information disclosure, such as cloud provider credentials or access to internal network services.

## Affected

- `guardrails-detectors < 985c6d5a4a84360ff8b447b94e4a3cdfbda3da90`
- `rhoai/odh-built-in-detector-rhel9 (all versions)`
- `rhoai/odh-guardrails-detector-huggingface-runtime-rhel9 (all versions)`
