{"cve":"CVE-2026-84200","nvd":{"published":"2026-09-01T12:17:49.540","modified":"2026-09-10T15:43:03.760","status":"Awaiting Analysis","description":"Kyverno versions v1.9.0 through v1.12.7 contain a policy exception handling flaw. 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.","cvss_v4":{"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},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":9.0},"cwes":["CWE-284"],"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","https://github.com/kyverno/kyverno/security/advisories/GHSA-gg4x-fgg2-h9w9"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:50:50.842544443+00:00"},"epss":{"cve":"CVE-2026-84200","score":0.00273,"percentile":0.19744,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-gg4x-fgg2-h9w9","url":"https://osv.dev/vulnerability/GHSA-gg4x-fgg2-h9w9","summary":"Bypassing Kyverno Policies via Double Policy Exceptions","modified":"2026-09-25T14:25:34.508134973Z","packages":[{"ecosystem":"Go","name":"github.com/kyverno/kyverno","purl":"pkg:golang/github.com/kyverno/kyverno","ranges":[">=1.9.0 <1.13.0"],"fixed":["1.13.0"]}]},{"id":"GO-2026-4285","url":"https://osv.dev/vulnerability/GO-2026-4285","summary":"Bypassing Kyverno Policies via Double Policy Exceptions in github.com/kyverno/kyverno","modified":"2026-09-25T14:25:34.508134973Z","packages":[{"ecosystem":"Go","name":"github.com/kyverno/kyverno","purl":"pkg:golang/github.com/kyverno/kyverno","ranges":[">=1.9.0 <1.13.0"],"fixed":["1.13.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
