| summary: Authentication bypass in go.etcd.io/etcd |
| description: |- |
| A user can use a valid client certificate that contains a CommonName that |
| matches a valid RBAC username to authenticate themselves as that user, despite |
| lacking the required credentials. This may allow authentication bypass, but |
| requires a certificate that is issued by a CA trusted by the server. |
