Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The go.etcd.io/etcd/client/v3 Go module is affected in versions before 3.3.23 and from 3.4.0 before 3.4.10. etcd does not enforce a minimum password length when creating or updating users, so an attacker with the ability to attempt logins could guess very short passwords more easily. Upgrade to version 3.3.23 or 3.4.10 or later; the source also says administrators should enforce password strength requirements themselves.
