Summary
keystone vulnerabilities
Details

Kay discovered that OpenStack Keystone incorrectly handled the ec2tokens and s3tokens APIs. A remote attacker could possibly use this issue to obtain unauthorized access and escalate privileges. (CVE-2025-65073)

It was discovered that OpenStack Keystone only validated the first 72 bytes of an application secret. An attacker could possibly use this issue to bypass password complexity. (CVE-2021-3563)

It was discovered that OpenStack Keystone had a time lag before a token should be revoked by the security policy. A remote administrator could use this issue to maintain access for longer than expected. (CVE-2022-2447)
