Hi,

The following vulnerability was published for etcd.

CVE-2026-59818[0]:
| etcd is a distributed key-value store for the data of a distributed
| system. Prior to 3.5.32 and 3.6.13, when etcd is configured with
| --listen-client-http-urls to split HTTP and gRPC client endpoints
| onto separate listeners, the --client-crl-file Certificate
| Revocation List is not enforced on the gRPC listener, allowing a
| client with a revoked certificate to authenticate successfully over
| gRPC. This issue is fixed in versions 3.5.32 and 3.6.13.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
