CVE-2026-122309

Kyverno before 1.19.2 contains a denial of service vulnerability that allows namespace-scoped policy authors to exhaust CPU and memory by submitting CEL expressions evaluated without runtime cost limits. Attackers can create a NamespacedValidatingPolicy or NamespacedDeletingPolicy with nested map...

EUVD-2026-117222

Kyverno from 1.16.0 before 1.19.2 fails to validate path segments in the resource argument of resource.get and resource.post, allowing namespaced CEL policies to escape their namespace. Tenants who can create a NamespacedValidatingPolicy can insert .. segments to read and write arbitrary cluster...

CVE-2026-122309

Kyverno versions before 1.19.2 are vulnerable to a Denial of Service (DoS) flaw caused by unbounded CEL policy evaluation costs . Specifically, namespace-scoped policy authors can exhaust CPU and memory by submitting CEL expressions that lack runtime cost limits. An attacker can exploit this by c...

CVE-2026-100703

Kyverno 1.16.0 through 1.19.0 registers the globalcontext.Lib CEL library in its policy environment without confining it to the policy's namespace, unlike the sibling libraries resource.Lib, http.Lib, configMap loader which are handed the policy namespace. A tenant who can create a namespaced...
