CVE-2024-48921

LOW

Kyverno < 1.13.0 - Improper Authorization via PolicyException Namespace Bypass

Title source: llm
STIX 2.1

Description

Kyverno is a policy engine designed for Kubernetes. A kyverno ClusterPolicy, ie. "disallow-privileged-containers," can be overridden by the creation of a PolicyException in a random namespace. By design, PolicyExceptions are consumed from any namespace. Administrators may not recognize that this allows users with privileges to non-kyverno namespaces to create exceptions. This vulnerability is fixed in 1.13.0.
