[A vulnerability](https://github.com/helm/helm/security/advisories/GHSA-7hfp-qfw3-5jxh) found in the Helm SDK allows for specific data inputs to cause high memory consumption, which in some platforms could cause the controller to panic and stop processing reconciliations.\n\n### Impact\nIn 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.\n\n### Credits\n\nThe initial crash bug was reported by [oss-fuzz](https://github.com/google/oss-fuzz). The Flux Security team produced the first exploit and worked together with the Helm Security team to ensure that both projects were patched timely.\n\n### For more information\n\nIf you have any questions or comments about this advisory:\n- Open an issue in any of the affected repositories.\n- Contact us at the CNCF Flux Channel.\n\n### References\n\n- https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=48360\n- https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=44996\n- https://github.com/helm/helm/security/advisories/GHSA-7hfp-qfw3-5jxh\n","published":"2022-09-07T20:15:13Z","modified":"2026-08-12T03:51:36.846612649Z","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"},{"type":"PACKAGE","url":"https://github.com/fluxcd/flux2"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:36.846612649Z"}}
