Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2014-5251 not yet assigned priority: Debian including 1 source packages (keystone), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
The MySQL token driver in OpenStack Identity (Keystone) 2014.1.x before 2014.1.2.1 and Juno before Juno-3 stores timestamps with the incorrect precision, which causes the expiration comparison for tokens to fail and allows remote authenticated users to retain access via an expired token.
