      <title>CVE-2026-84200 — Kyverno before v1.13.0 Policy Bypass via Multiple Exceptions</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-84200</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; kyverno&lt;/p&gt;
&lt;p&gt;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&amp;#39;s name pattern (e.g., &amp;#39;*ingress*&amp;#39;). This can be used to circumvent policies such as one blocking hostPath volumes. Fixed in v1.13.0.&lt;/p&gt;</description>
