{"id":"CVE-2022-39272","state":"PUBLISHED","title":"Flux2 vulnerable to Denial of Service due to Improper use of metav1.Duration","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.","publishedAt":"2022-10-21T00:00:00.000Z","updatedAt":"2025-04-23T16:45:22.608Z","severity":{"score":5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["fluxcd flux2"],"affected":[{"vendor":"fluxcd","product":"flux2","versions":[{"version":"< 0.35.0","status":"affected"}]}],"references":["https://github.com/fluxcd/flux2/security/advisories/GHSA-f4p5-x4vc-mh4v","https://github.com/kubernetes/apimachinery/issues/131"],"weaknesses":["CWE-1284"],"ingestedAt":"2026-10-29T19:50:29.496Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2022/39xxx/CVE-2022-39272.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2022-39272","state":"PUBLISHED","datePublished":"2022-10-21T00:00:00.000Z","dateUpdated":"2025-04-23T16:45:22.608Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2022-09-02T00:00:00.000Z"},"containers":{"cna":{"title":"Flux2 vulnerable to Denial of Service due to Improper use of metav1.Duration","descriptions":[{"lang":"en","value":"Flux is an open and extensible continuous delivery solution for Kubernetes.
