{"cve":"CVE-2022-39272","nvd":{"published":"2022-10-22T00:15:09.310","modified":"2026-06-17T04:58:02.757","status":"Modified","description":"Flux is an open and extensible continuous delivery solution for Kubernetes. Versions prior to 0.35.0 are subject to a Denial of Service. Users that have permissions to change Flux’s objects, either through a Flux source or directly within a cluster, can provide invalid data to fields `.spec.interval` or `.spec.timeout` (and structured variations of these fields), causing the entire object type to stop being processed. This issue is patched in version 0.35.0. As a workaround, Admission controllers can be employed to restrict the values that can be used for fields `.spec.interval` and `.spec.timeout`, however upgrading to the latest versions is still the recommended mitigation.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L","score":4.3},"cwes":["CWE-1284"],"references":["https://github.com/fluxcd/flux2/security/advisories/GHSA-f4p5-x4vc-mh4v","https://github.com/kubernetes/apimachinery/issues/131","https://github.com/fluxcd/flux2/security/advisories/GHSA-f4p5-x4vc-mh4v","https://github.com/kubernetes/apimachinery/issues/131"],"products":["fluxcd:flux2","fluxcd:helm-controller","fluxcd:image-automation-controller","fluxcd:image-reflector-controller","fluxcd:kustomize-controller","fluxcd:notification-controller","fluxcd:source-controller"],"source":"nvd","synced_at":"2026-10-19T21:37:08.729216836+00:00"},"epss":{"cve":"CVE-2022-39272","score":0.00769,"percentile":0.55627,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-f4p5-x4vc-mh4v","url":"https://osv.dev/vulnerability/GHSA-f4p5-x4vc-mh4v","summary":"Improper
