Credential disclosure via copiedFrom label authorization bypass
Published Aug 12, 2026 · Updated Aug 25, 2026
Authorization bypass in Red Hat multicluster engine for Kubernetes allows remote authenticated users to intercept rotated provider credentials. The reconcileProviderCredentials function lists Secrets cluster-wide by copiedFrom labels and treats a SHA-256 match against the source Secret's prior data as the sole authorization check. Exploitation requires secrets:create in any hub namespace, the byte-exact prior credential value, and an administrator-triggered rotation; it discloses the newly rotated provider credential.
