CVE-2022-2447: Openstack Keystone

Medium severity, CVSS 6.6. EPSS: 0.7% chance of exploitation in the next 30 days.

A flaw was found in Keystone. There is a time lag (up to one hour in a default configuration) between when security policy says a token should be revoked from when it is actually revoked. This could allow a remote administrator to secretly maintain access for longer than expected.
