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.\n\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).\n\n### Patches\n\nThis issue has been patched in Helm 2.16.11 and Helm 3.3.2.\n\n### Workarounds\n\nMake sure to install plugins using a secure connection protocol like SSL.","affected":[{"package":{"name":"helm.sh/helm/v3","ecosystem":"Go","purl":"pkg:golang/helm.sh/helm/v3"},"ranges":[{"type":"SEMVER","events":[{"introduced":"3.0.0"},{"fixed":"3.3.2"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/05/GHSA-c52f-pq47-2r9j/GHSA-c52f-pq47-2r9j.json"}},{"package":{"name":"helm.sh/helm","ecosystem":"Go","purl":"pkg:golang/helm.sh/helm"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.0.0"},{"fixed":"2.16.11"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/05/GHSA-c52f-pq47-2r9j/GHSA-c52f-pq47-2r9j.json"}}],"references":[{"type":"WEB","url":"https://github.com/helm/helm/security/advisories/GHSA-c52f-pq47-2r9j"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-15187"},{"type":"WEB","url":"https://github.com/helm/helm/commit/6aab63765f99050b115f0aec3d6350c85e8da946"},{"type":"WEB","url":"https://github.com/helm/helm/commit/ac7c07c37d87e09797f714fb57aa5e9cb99d9450"},{"type":"WEB","url":"https://github.com/helm/helm/commit/b0296c0522e837d65f944beefa3fb64fd08ac304"},{"type":"WEB","url":"https://github.com/helm/helm/commit/c8d6b01d72c9604e43ee70d0d78fadd54c2d8499"},{"type":"WEB","url":"https://github.com/helm/helm/commit/d9ef5ce8bad512e325390c0011be1244b8380e4b"},{"type":"WEB","url":"https://github.com/helm/helm/commit/f2ede29480b507b7d8bb152dd8b6b86248b00658"},{"type":"PACKAGE","url":"https://github.com/helm/helm"}],"database_specific":{"cwe_ids":["CWE-694","CWE-74"],"github_reviewed":true,"github_reviewed_at":"2021-05-24T12:56:32Z","nvd_published_at":"2020-09-17T22:15:00Z","severity":"LOW"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:N/I:L/A:N"}]}
