{"apiVersion":"1.0","identifier":"CVE-2026-66793","description":"A flaw was found in the governance-policy-addon-controller component of Red Hat Advanced Cluster Management for Kubernetes. A user with permissions to annotate the namespaced ManagedClusterAddOn resource can override the governance-policy container image. This allows an attacker to run a controlled image with cluster-admin privileges on the managed cluster, leading to arbitrary code execution and privilege escalation.","publishedAt":"2026-08-18T15:17:00","lastModifiedAt":"2026-08-27T04:16:46","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-66793","cvssScore":8.8,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00755,"riskScore":0.94,"affectedProduct":"Red Hat Advanced Cluster Management for Kubernetes","affectedVersions":"unknown","vulnerabilityType":"Other","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-66793","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-66793","en":"https://www.redsauce.net/en/cves/CVE-2026-66793","fr":"https://www.redsauce.net/fr/cves/CVE-2026-66793","pt":"https://www.redsauce.net/pt/cves/CVE-2026-66793","de":"https://www.redsauce.net/de/cves/CVE-2026-66793","sk":"https://www.redsauce.net/sk/cves/CVE-2026-66793","el":"https://www.redsauce.net/el/cves/CVE-2026-66793"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-66793"}}
