Detailsinfo

A vulnerability classified as critical has been found in Kyverno up to 1.12.7. Affected is an unknown code block of the component Policy Exception Handler. The manipulation with an unknown input leads to a privileges management vulnerability. CWE is classifying the issue as CWE-269.

This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.
