CVE-2025-25209

Secret disclosure via cross-namespace SharedSecretRef resolution

Published Jun 9, 2025 · Updated Mar 26, 2026

Information disclosure in Red Hat Connectivity Link 1.0.1 allows remote authenticated users to expose Kubernetes secrets over HTTP. AuthPolicy metadata resolves a sharedSecretRef in the kuadrant-system namespace instead of copying and scoping the referenced Secret to the policy namespace. A developer persona must know the target Secret name, and only single-line Secret values can be disclosed through the resulting request.
