• Sep 19, 2026 Security dex-app v3.2.1

  Fixed

  • A pre-defined static client (gitopsui, muster, mcpKubernetes, mcpCapi, mcpPrometheus) with a clientID and neither clientSecret nor clientSecretRef is left out of the dex configuration again, as before v3.1.0, and named in the release notes, instead of failing the render: values shared by several installations can declare a client whose secret only some of them carry. Both sources on one client still fail the render naming the client; dex-k8s-authenticator and extra static clients that are not public still need exactly one. Clients with a secret render unchanged.
