Red Hat Security Advisory: Red Hat OpenStack Platform 17.1 (openstack-keystone) security update
Red Hat OpenStack Platform 17.1 (openstack-keystone) contains security vulnerabilities that allow privilege escalation through EC2 credential creation and unauthorized access to EC2/S3 token endpoints. These issues could grant unauthorized Keystone authorization. Red Hat has released updates addressing these vulnerabilities.
AI Analysis
Technical Summary
Two security vulnerabilities affect Red Hat OpenStack Platform 17.1's Keystone service: CVE-2026-33551 allows privilege escalation via EC2 credential creation, and CVE-2025-65073 permits unauthenticated access to EC2/S3 token endpoints potentially granting Keystone authorization. Keystone is the Python implementation of the OpenStack identity service API. These vulnerabilities relate to improper authorization and access control mechanisms in Keystone's handling of AWS signature validation and token endpoints.
Potential Impact
Exploitation of these vulnerabilities could allow an attacker to escalate privileges within the OpenStack Keystone service or gain unauthorized authorization tokens, potentially compromising identity and access management within affected OpenStack deployments. The severity is rated as high by the source, but Red Hat rates the update as having a low security impact in their advisory.
Mitigation Recommendations
Red Hat has released updated packages for openstack-keystone (version 19.0.2-17.1.20260529190847.54dd95d.el9ost) that address these vulnerabilities. Users of Red Hat OpenStack Platform 17.1 should apply these official updates promptly. For detailed update instructions, refer to Red Hat's advisory at https://access.redhat.com/articles/11258. Patch status is confirmed as fixed in version 19.0.2 and later. No cloud service remediation applies as this is not a cloud-hosted service.
