In Helm versions <=3.20.1 and <=4.1.3, a specially crafted Chart will cause helm pull --untar  [chart URL | repo/chartname] to write the Chart's contents to the immediate output directory (as defaulted to the current working directory; or as given by the --destination and --untardir flags), rather than the expected output directory suffixed by the chart's name. This vulnerability is fixed in 3.20.2 and 4.1.4.","published":"2026-04-09T21:02:13.594Z","modified":"2026-07-24T19:11:42.050769392Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"helm.sh/helm/v4","fixedVersion":"4.1.4"},{"ecosystem":"Go","name":"helm.sh/helm/v3","fixedVersion":"3.20.2"}],"fix":{"url":"https://github.com/helm/helm/commit/4e7994d4467182f535b6797c94b5b0e994a91436","label":"helm/helm@4e7994d"},"references":[{"type":"WEB","url":"https://github.com/helm/helm/releases/tag/v4.1.4"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35206.json"},{"type":"ADVISORY","url":"https://github.com/helm/helm/security/advisories/GHSA-hr2v-4r36-88hr"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35206"},{"type":"FIX","url":"https://github.com/helm/helm/commit/4e7994d4467182f535b6797c94b5b0e994a91436"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-24T19:11:42.050769392Z"}}
