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 and unauthorized access via EC2/S3 token endpoints. These issues are addressed in a security update provided by Red Hat. The vulnerabilities involve improper authorization checks in the Keystone identity service API, potentially allowing attackers to gain elevated privileges or unauthorized access.
AI Analysis
Technical Summary
Two security vulnerabilities affect Red Hat OpenStack Platform 17.1's Keystone component: CVE-2026-33551 allows privilege escalation through EC2 credential creation, and CVE-2025-65073 permits unauthenticated access to EC2/S3 token endpoints that can grant Keystone authorization. Keystone is the Python implementation of the OpenStack identity service API. These flaws stem from authorization weaknesses in handling AWS signature validation and token endpoint access. Red Hat has issued a security advisory (RHSA-2026:28044) with updates to mitigate these issues.
Potential Impact
Successful exploitation of these vulnerabilities could allow an attacker to escalate privileges within the OpenStack Keystone service or gain unauthorized access to Keystone authorization tokens. This could lead to unauthorized control over identity management functions in OpenStack environments running the affected versions. The severity is rated as high by the source, indicating significant security impact if exploited.
Mitigation Recommendations
Red Hat has released updated packages for openstack-keystone to address these vulnerabilities. Users of Red Hat OpenStack Platform 17.1 should apply the security update as described in Red Hat advisory RHSA-2026:28044. Detailed update instructions are available at https://access.redhat.com/articles/11258. No indication of automatic or cloud service patching is provided, so manual update is required. Patch status is confirmed by the vendor advisory.
