USN-7926-1: OpenStack Keystone vulnerabilities

Ubuntu December 11, 2025

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 )
