{"apiVersion":"1.0","identifier":"CVE-2026-66795","description":"A flaw was found in the managedcluster-import-controller. The Certificate Signing Request (CSR) auto-approval logic improperly validates incoming CSRs, specifically by not inspecting the signer name or decoding the PEM-encoded x509 CSR. This vulnerability allows a privileged service account on a spoke cluster to submit a malicious CSR. Successful exploitation can lead to privilege escalation, enabling the attacker to obtain administrative credentials on the hub cluster.","publishedAt":"2026-08-17T21:16:47","lastModifiedAt":"2026-08-25T21:17:36","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-66795","cvssScore":9.1,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","epssProbability":0.00351,"riskScore":0.94,"affectedProduct":"managedcluster-import-controller","affectedVersions":"unknown","vulnerabilityType":"Other","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-66795","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-66795","en":"https://www.redsauce.net/en/cves/CVE-2026-66795","fr":"https://www.redsauce.net/fr/cves/CVE-2026-66795","pt":"https://www.redsauce.net/pt/cves/CVE-2026-66795","de":"https://www.redsauce.net/de/cves/CVE-2026-66795","sk":"https://www.redsauce.net/sk/cves/CVE-2026-66795","el":"https://www.redsauce.net/el/cves/CVE-2026-66795"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-66795"}}
