CVE-2026-15378 Red Hat CVE debrief
A critical vulnerability was found in the `guardrails-detectors` component, allowing 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. The CVE record was published on 2026-07-10T10:16:23.553Z and has not been modified since then.
