CVE-2026-84200: Kyverno

Critical severity, CVSS 9.0. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Kyverno Kyverno: before 1.13.0 (fixed in 1.13.0)
