When a policy in enforce mode is combined with two PolicyExceptions, the less restrictive exception takes precedence, allowing an attacker to bypass the policy by crafting a resource name that matches the second exception's name pattern (e.g., '*ingress*'). This can be used to circumvent policies such as one blocking hostPath volumes. Fixed in v1.13.0.","state":0,"publishedAt":"2026-09-01T11:34:00.464+00:00","modifiedAt":"2026-09-02T17:48:14.423+00:00","affected":[{"ecosystem":"Vendor product","name":"kyverno","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"kyverno\",\n                    \"product\": \"kyverno\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageURL\": \"pkg:golang/github.com/kyverno/kyverno\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"1.13.0\"\n                        },\n                        {\n                            \"version\": \"1.13.0\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","score":9.4,"severity":"CRITICAL"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":9,"severity":"CRITICAL"}],"references":["https://github.com/kyverno/kyverno/security/advisories/GHSA-gg4x-fgg2-h9w9","https://www.vulncheck.com/advisories/kyverno-before-1.13.0-policy-bypass-via-multiple-exceptions"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-84200","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-84200","identifiers":["CVE-2026-84200"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
