GHSA-4993-m7g5-r9hh etcd has no minimum password length

• Go go.etcd.io/etcd/client/v3: >= 3.4.0, < 3.4.10 → fixed in 3.4.10 • Go go.etcd.io/etcd/client/v3: < 3.3.23 → fixed in 3.3.23

Vulnerability type Access Control Workarounds The etcdctl and etcd API do not enforce a specific password length during user creation or user password update operations. It is the responsibility of the administrator to enforce these requirements. Detail etcd does not perform any password length validation, which allows for very short passwords, such as those with a length of one. This may allow an attacker to guess or brute-force users’ passwords with little computational effort.
