{"id":"CVE-2026-35206","summary":"Helm Chart extraction output directory collapse via `Chart.yaml` name dot-segment","details":"Helm is a package manager for Charts for Kubernetes. In Helm versions \u003c=3.20.1 and \u003c=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.","aliases":["BIT-helm-2026-35206","GHSA-hr2v-4r36-88hr"],"modified":"2026-06-18T03:57:16.974467125Z","published":"2026-04-09T21:02:13.594Z","related":["CGA-2fmw-fc3p-8vp3","SUSE-SU-2026:1483-1","SUSE-SU-2026:21434-1","SUSE-SU-2026:21461-1","SUSE-SU-2026:21628-1","SUSE-SU-2026:21635-1","openSUSE-SU-2026:10532-1","openSUSE-SU-2026:10538-1","openSUSE-SU-2026:20655-1"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-22"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35206.json"},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/helm/helm","events":[{"introduced":"0"},{"fixed":"8fb76d6ab555577e98e23b7500009537a471feee"},{"introduced":"99cd1964357c793351be481d55abbe21c6b2f4ec"},{"fixed":"05fa37973dc9e42b76e1d2883494c87174b6074f"},{"fixed":"4e7994d4467182f535b6797c94b5b0e994a91436"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"3.20.2"},{"introduced":"4.0.0"},{"fixed":"4.1.4"}],"cpe":"cpe:2.3:a:helm:helm:*:*:*:*:*:*:*:*","source":["CPE_RANGE","REFERENCES"]}}],"versions":["v3.20.1","v4.1.3","v3.20.0-rc.1","v3.20.0","v4.1.2","v4.1.1","v4.1.0-rc.1","v4.1.0","v4.0.0-rc.1","v4.0.0","v3.12.0-dev.1","v3.0.0-beta.5","v3.0.0-beta.4","v3.0.0-beta.3","v3.0.0-beta.2","v3.0.0-beta.1","v3.0.0-alpha.2","v3.0.0-alpha.1","v2.8.0-rc.1","v2.7.0","v2.7.0-rc1","v2.6.0","v2.5.0","v2.4.0","v2.3.0","v2.2.0","v2.1.0","v2.0.0","v2.0.0-rc.2","v2.0.0-rc.1","v2.0.0-beta.2","v2.0.0-beta.1","v2.0.0-alpha.5","v2.0.0-alpha.4","v2.0.0-alpha.2","v2.0.0-alpha.1","1.999.0","v1.2","v1.1","v1.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-35206.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N"}]}
