CVSS 3.0
5.3 mediumCVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:NCVE-2018-20170
Medium (5.3) in openstack keystone. EPSS 1.1% chance of exploitation in the next 30 days. Fixed in keystone 14.1.0.
OpenStack Keystone through 14.0.1 has a user enumeration vulnerability because invalid usernames have much faster responses than valid ones for a POST /v3/auth/tokens request. NOTE: the vendor's position is that this is a hardening opportunity, and not necessarily an issue that should have an OpenStack Security Advisory
