CVE-2026-15378
CRITICALCVE-2026-15378 enables blind SSRF in guardrails-detectors to exfiltrate cloud metadata, Kubernetes secrets, and internal endpoints.
This critical flaw allows remote attackers to perform blind SSRF via crafted XML Schema Definition strings, exposing cloud metadata, Kubernetes API credentials, MinIO, and pod secrets. DIB orgs must patch immediately as it bypasses security controls and enables unauthorized access to sensitive infrastructure data.
Shame score — A critical SSRF vulnerability in a security component that exposes cloud metadata and secrets, though not yet exploited in the wild.
▸ RECOMMENDED ACTION Critical severity — schedule patching of the affected products.
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.
