{"cve":"CVE-2020-15187","nvd":{"published":"2020-09-17T22:15:12.647","modified":"2026-06-17T02:56:13.427","status":"Modified","description":"In Helm before versions 2.16.11 and 3.3.2, a Helm plugin can contain duplicates of the same entry, with the last one always used. If a plugin is compromised, this lowers the level of access that an attacker needs to modify a plugin's install hooks, causing a local execution attack.\nTo perform this attack, an attacker must have write access to the git repository or plugin archive (.tgz) while being downloaded (which can occur during a MITM attack on a non-SSL connection). This issue has been patched in Helm 2.16.11 and Helm 3.3.2.\nAs a possible workaround make sure to install plugins using a secure connection protocol like SSL.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:L","score":4.7},"cwes":["CWE-74","CWE-694"],"references":["https://github.com/helm/helm/commit/6aab63765f99050b115f0aec3d6350c85e8da946","https://github.com/helm/helm/commit/ac7c07c37d87e09797f714fb57aa5e9cb99d9450","https://github.com/helm/helm/commit/b0296c0522e837d65f944beefa3fb64fd08ac304","https://github.com/helm/helm/commit/c8d6b01d72c9604e43ee70d0d78fadd54c2d8499","https://github.com/helm/helm/commit/d9ef5ce8bad512e325390c0011be1244b8380e4b"],"products":["helm:helm"],"source":"nvd","synced_at":"2026-10-19T21:09:53.489947993+00:00"},"epss":{"cve":"CVE-2020-15187","score":0.01517,"percentile":0.74544,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-c52f-pq47-2r9j","url":"https://osv.dev/vulnerability/GHSA-c52f-pq47-2r9j","summary":"plugin.yaml file allows for duplicate entries in helm","modified":"2026-07-08T06:00:54.727183803Z","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":[">=2.0.0 <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).
