CVE NOT AVAILABLE CWE-918  (opens in a new tab)

How to fix?

There is no fixed version for github.com/etcd-io/etcd/server/etcdserver.

Overview

Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) when adding a new member. If users provide a malicious peer URL, the existing etcd members may be redirected to another unexpected internal URL when getting the new member's version.

Note This vulnerability is unlikely to be exploited because usually, the communication between clients and etcd cluster is protected by TLS. So, there is no way for a malicious client to add a member with a malicious peer URL as long as the client doesn't have a valid certificate to communicate with the etcd cluster.
