In versions of Kyverno prior to 1.10.0, resources which have the `deletionTimestamp` field defined can bypass validate, generate, or mutate-existing policies, even in cases where the `validationFailureAction` field is set to `Enforce`. This situation occurs as resources pending deletion were being consciously exempted by Kyverno, as a way to reduce processing load as policies are typically not applied to objects which are being deleted. However, this could potentially result in allowing a malicious user to leverage the Kubernetes finalizers feature by setting a finalizer which causes the Kubernetes API server to set the `deletionTimestamp` and then not completing the delete operation as a way to explicitly to bypass a Kyverno policy. Note that this is not applicable to Kubernetes Pods but, as an example, a Kubernetes Service resource can be manipulated using an indefinite finalizer to bypass policies. This is resolved in Kyverno 1.10.0. There is no known workaround."}],"source":{"advisory":"GHSA-hq4m-4948-64cc","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T16:01:53.601Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/kyverno/kyverno/security/advisories/GHSA-hq4m-4948-64cc","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/kyverno/kyverno/security/advisories/GHSA-hq4m-4948-64cc"},{"name":"https://github.com/kyverno/kyverno/releases/tag/v1.10.0","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/kyverno/kyverno/releases/tag/v1.10.0"}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2025-01-08T21:32:38.963338Z","id":"CVE-2023-34091","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-01-08T21:32:51.451Z"}}]}}
