{"id":"CVE-2022-36049","aliases":["BIT-flux-2022-36049","BIT-helm-2022-36049","GHSA-p2g7-xwvr-rrw3"],"url":"https://o3.security/vulnerability/CVE-2022-36049","summary":"Flux2 Helm Controller denial of service","details":"Flux2 is a tool for keeping Kubernetes clusters in sync with sources of configuration, and Flux's helm-controller is a Kubernetes operator that allows one to declaratively manage Helm chart releases. Helm controller is tightly integrated with the Helm SDK. A vulnerability found in the Helm SDK that affects flux2 v0.0.17 until v0.32.0 and helm-controller v0.0.4 until v0.23.0 allows for specific data inputs to cause high memory consumption. In some platforms, this could cause the controller to panic and stop processing reconciliations. In a shared cluster multi-tenancy environment, a tenant could create a HelmRelease that makes the controller panic, denying all other tenants from their Helm releases being reconciled. Patches are available in flux2 v0.32.0 and helm-controller v0.23.0.","published":"2022-09-07T20:15:13Z","modified":"2026-08-04T05:32:27.904048272Z","cvss":{"score":7.7,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/fluxcd/helm-controller","fixedVersion":"0.23.0"},{"ecosystem":"Go","name":"github.com/fluxcd/flux2","fixedVersion":"0.32.0"}],"fix":null,"references":[{"type":"WEB","url":"https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=44996"},{"type":"WEB","url":"https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=48360"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/36xxx/CVE-2022-36049.json"},{"type":"ADVISORY","url":"https://github.com/fluxcd/flux2/security/advisories/GHSA-p2g7-xwvr-rrw3"},{"type":"ADVISORY","url":"https://github.com/helm/helm/security/advisories/GHSA-7hfp-qfw3-5jxh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-36049"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-04T05:32:27.904048272Z"}}
