AI-Generated

A critical vulnerability in the `guardrails-detectors` component of Kubernetes allows remote attackers to execute blind Server-Side Request Forgery (SSRF) through a specially crafted XML Schema Definition (XSD) string. This can result in unauthorized access to sensitive information, including cloud metadata credentials and internal network resources, as well as the potential for local file reads of critical data like service account tokens and pod secrets. Organizations using Kubernetes should prioritize patching this vulnerability to mitigate the risk of data breaches and unauthorized access.

Original NVD Description

A flaw was found in the `guardrails-detectors` component. This vulnerability allows a remote attacker to perform a blind Server-Side Request Forgery (SSRF) by submitting a specially crafted XML Schema Definition (XSD) string. This can lead to unauthorized access to sensitive information, including credentials from cloud metadata services, Kubernetes API, internal MinIO, and other internal network endpoints. Additionally, it enables local file reads of critical data such as service account tokens and pod secrets.
