As a result, a malicious plugin author could use characters in a plugin name that would result in unexpected behavior, such as duplicating the name of another plugin or spoofing the output to `helm --help`. This issue has been patched in Helm 3.3.2. A possible workaround is to not install untrusted Helm plugins. Examine the `name` field in the `plugin.yaml` file for a plugin, looking for characters outside of the [a-zA-Z0-9._-] range.","affected":[{"package":{"name":"helm","ecosystem":"Bitnami","purl":"pkg:bitnami/helm"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.0.0"},{"fixed":"2.16.11"},{"introduced":"3.0.0"},{"fixed":"3.3.2"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/helm/BIT-helm-2020-15186.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:N"}]}],"references":[{"type":"ADVISORY","url":"https://github.com/helm/helm/commit/809e2d999e2c33e20e77f6bff30652d79c287542"},{"type":"ADVISORY","url":"https://github.com/helm/helm/security/advisories/GHSA-m54r-vrmv-hw33"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-15186"}],"database_specific":{"cpes":["cpe:2.3:a:helm:helm:*:*:*:*:*:*:*:*"],"severity":"Low"}}
