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.","title":"Description of the CVE"},{"category":"legal_disclaimer","text":"CSAF 2.0 data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).","title":"Terms of use"}],"publisher":{"category":"vendor","contact_details":"https://www.suse.com/support/security/contact/","name":"SUSE Product Security Team","namespace":"https://www.suse.com/"},"references":[{"category":"external","summary":"CVE-2023-34091","url":"https://www.suse.com/security/cve/CVE-2023-34091"},{"category":"external","summary":"SUSE Security Ratings","url":"https://www.suse.com/support/security/rating/"},{"category":"external","summary":"SUSE Bug 1211943 for CVE-2023-34091","url":"https://bugzilla.suse.com/1211943"}],"title":"SUSE CVE CVE-2023-34091","tracking":{"current_release_date":"2025-02-16T06:17:33Z","generator":{"date":"2023-06-03T02:13:21Z","engine":{"name":"cve-database.git:bin/generate-csaf-vex.pl","version":"1"}},"id":"CVE-2023-34091","initial_release_date":"2023-06-03T02:13:21Z","revision_history":[{"date":"2023-06-03T02:13:21Z","number":"2","summary":"Current version"},{"date":"2025-01-01T02:03:57Z","number":"3","summary":"Current version"},{"date":"2025-02-14T06:24:24Z","number":"4","summary":"Current version"},{"date":"2025-02-16T06:17:33Z","number":"5","summary":"Current version"}],"status":"interim","version":"5"}}}
