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.","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-2020-15187.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:L"}]}],"references":[{"type":"ADVISORY","url":"https://github.com/helm/helm/commit/d9ef5ce8bad512e325390c0011be1244b8380e4b"},{"type":"ADVISORY","url":"https://github.com/helm/helm/security/advisories/GHSA-c52f-pq47-2r9j"},{"type":"WEB","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/f2ede29480b507b7d8bb152dd8b6b86248b00658"}],"database_specific":{"cpes":["cpe:2.3:a:helm:helm:*:*:*:*:*:*:*:*"],"severity":"Medium"}}
