CVE-2020-15115: Weak Password Requirements

August 6, 2020 (updated January 4, 2021)

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.
