{"apiVersion":"1.0","identifier":"CVE-2026-73267","description":"A flaw was found in the clusterclaims-controller component of multicluster engine (MCE). A tenant with standard permissions to create and delete ClusterClaim resources can exploit this by manipulating the `spec.namespace` field. This allows the tenant to specify and delete any ManagedCluster, including the hub-s local-cluster or other tenants- clusters, due to a missing ownership check. This vulnerability can lead to a denial of service by enabling unauthorized deletion of ManagedClusters.","publishedAt":"2026-08-21T03:16:39","lastModifiedAt":"2026-08-25T21:17:45","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-73267","cvssScore":7.7,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H","epssProbability":0.00462,"riskScore":0.8,"affectedProduct":"multicluster engine","affectedVersions":"unknown","vulnerabilityType":"Other","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-73267","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-73267","en":"https://www.redsauce.net/en/cves/CVE-2026-73267","fr":"https://www.redsauce.net/fr/cves/CVE-2026-73267","pt":"https://www.redsauce.net/pt/cves/CVE-2026-73267","de":"https://www.redsauce.net/de/cves/CVE-2026-73267","sk":"https://www.redsauce.net/sk/cves/CVE-2026-73267","el":"https://www.redsauce.net/el/cves/CVE-2026-73267"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-73267"}}
