CVE-2026-73266
HIGH7.1
CVSS v3
Description
A flaw was found in the clusterclaims-controller component of Multicluster Engine (MCE). An authenticated tenant can exploit this vulnerability by manipulating ClusterClaim labels. This allows the tenant to force a cluster to join a ManagedClusterSet belonging to another tenant. Such unauthorized access could enable the injection of policies and workloads into other tenants' clusters.

Common questions
How do I fix CVE-2026-73266?
Published advisories record a fix for 52 affected products. The "How to fix" section on this page lists the fixed version and source advisory for each one, so apply the entry matching what you actually run.
Is CVE-2026-73266 being actively exploited?
Not that we know of. CVE-2026-73266 is not in the CISA Known Exploited Vulnerabilities catalog. Its EPSS score of 0.21% is the estimated probability that it will be exploited in the next 30 days. That is higher than 12% of all scored CVEs.
How severe is CVE-2026-73266?
CVE-2026-73266 has a CVSS v3 base score of 7.1, rated high. CVSS rates the technical impact if the vulnerability is exploited, not how likely that is, so weigh it alongside the exploit-prediction score when you decide what to patch first.
What does CVE-2026-73266 affect?
Published advisories record a fix for registry.redhat.io/multicluster (Red Hat / RHEL), registry.redhat.io/multicluster (Rocky), registry.redhat.io/multicluster-engine/addon (Rocky), registry.redhat.io/multicluster-engine/addon (Red Hat / RHEL), and 48 more. Only products with a sourced advisory are listed, so treat this as what we can cite rather than a complete inventory.
