The etcd gRPC client listener is affected by CVE-2026-59818, a vulnerability where it fails to properly enforce Certificate Revocation Lists (CRLs) when the `--client-crl-file` flag is used, potentially allowing clients with revoked certificates to bypass authentication and gain unauthorized access to etcd instances.
