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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-770","CWE-400"],"references":["https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=44996","https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=48360","https://github.com/fluxcd/flux2/security/advisories/GHSA-p2g7-xwvr-rrw3","https://github.com/helm/helm/security/advisories/GHSA-7hfp-qfw3-5jxh","https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=44996"],"products":["fluxcd:flux2","fluxcd:helm-controller","helm:helm"],"source":"nvd","synced_at":"2026-10-19T21:35:14.992143698+00:00"},"epss":{"cve":"CVE-2022-36049","score":0.01446,"percentile":0.73295,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-p2g7-xwvr-rrw3","url":"https://osv.dev/vulnerability/GHSA-p2g7-xwvr-rrw3","summary":"Helm Controller denial of service","modified":"2026-02-04T02:59:17.730653Z","packages":[{"ecosystem":"Go","name":"github.com/fluxcd/helm-controller","purl":"pkg:golang/github.com/fluxcd/helm-controller","ranges":[">=0.0.4 <0.23.0"],"fixed":["0.23.0"]},{"ecosystem":"Go","name":"github.com/fluxcd/flux2","purl":"pkg:golang/github.com/fluxcd/flux2","ranges":[">=0.0.17 <0.32.0"],"fixed":["0.32.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
