CVE-2026-35206
Last modified
CVE-2026-35206 is a medium-severity vulnerability rated 4.8/10 on the CVSS scale. Helm is a package manager for Charts for Kubernetes. 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. EPSS estimates a 0.20% chance of exploitation in the next 30 days.
