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.","published":"2026-09-01T12:17:49.540","modified":"2026-09-01T12:17:49.540","cvss":{"score":9,"severity":"CRITICAL","vector":"CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/kyverno/kyverno/security/advisories/GHSA-gg4x-fgg2-h9w9"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/kyverno-before-1.13.0-policy-bypass-via-multiple-exceptions"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-01T12:17:49.540"}}
