Technical Analysis

The Red Hat OpenStack Keystone component in OpenStack Services on OpenShift 18.0 has three identified vulnerabilities: CVE-2026-43001 allows unauthorized cross-project access due to improper validation during EC2 credential creation; CVE-2026-40683 permits unauthorized access because of incorrect handling of LDAP user status; and CVE-2026-33551 enables privilege escalation through EC2 credential creation. These vulnerabilities affect the identity service API implementation in Keystone. Red Hat has issued a security advisory RHSA-2026:39808 with updates to mitigate these issues.

Potential Impact

These vulnerabilities can lead to unauthorized access across projects, unauthorized access due to LDAP user status mishandling, and privilege escalation within the OpenStack Keystone service. This compromises the integrity and security of identity management in OpenStack deployments using Red Hat OpenStack Services on OpenShift 18.0, potentially allowing attackers to gain elevated privileges or access resources they should not have.

Mitigation Recommendations

Red Hat has released an important security update for openstack-keystone in Red Hat OpenStack Services on OpenShift 18.0. Users should apply the update as described in the Red Hat advisory RHSA-2026:39808 and the referenced article https://access.redhat.com/articles/11258 to remediate these vulnerabilities. No indication is given that no action is required or that the issues are already mitigated; therefore, applying the official update is recommended.
