{"cve":"CVE-2020-15186","nvd":{"published":"2020-09-17T22:15:12.520","modified":"2026-06-17T02:56:13.313","status":"Modified","description":"In Helm before versions 2.16.11 and 3.3.2 plugin names are not sanitized properly. 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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:N","score":2.7},"cwes":["CWE-74","CWE-20"],"references":["https://github.com/helm/helm/commit/809e2d999e2c33e20e77f6bff30652d79c287542","https://github.com/helm/helm/security/advisories/GHSA-m54r-vrmv-hw33","https://github.com/helm/helm/commit/809e2d999e2c33e20e77f6bff30652d79c287542","https://github.com/helm/helm/security/advisories/GHSA-m54r-vrmv-hw33"],"products":["helm:helm"],"source":"nvd","synced_at":"2026-10-19T21:09:53.489947993+00:00"},"epss":{"cve":"CVE-2020-15186","score":0.00962,"percentile":0.61651,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-m54r-vrmv-hw33","url":"https://osv.dev/vulnerability/GHSA-m54r-vrmv-hw33","summary":"Improper Sanitizing of plugin names in helm","modified":"2026-07-08T06:28:31.540338500Z","packages":[{"ecosystem":"Go","name":"helm.sh/helm/v3","purl":"pkg:golang/helm.sh/helm/v3","ranges":[">=3.0.0 <3.3.2"],"fixed":["3.3.2"]},{"ecosystem":"Go","name":"helm.sh/helm","purl":"pkg:golang/helm.sh/helm","ranges":["<2.16.11"],"fixed":["2.16.11"]}]}],"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).
