{"id":"CVE-2020-15185","aliases":["BIT-helm-2020-15185","GHSA-jm56-5h66-w453"],"url":"https://o3.security/vulnerability/CVE-2020-15185","summary":"Repository index file allows for duplicates of the same chart entry in helm","details":"In Helm before versions 2.16.11 and 3.3.2, a Helm repository can contain duplicates of the same chart, with the last one always used. If a repository is compromised, this lowers the level of access that an attacker needs to inject a bad chart into a repository. To perform this attack, an attacker must have write access to the index file (which can occur during a MITM attack on a non-SSL connection). This issue has been patched in Helm 3.3.2 and 2.16.11. A possible workaround is to manually review the index file in the Helm repository cache before installing software.","published":"2020-09-17T22:15:12.443Z","modified":"2026-07-09T10:21:09.702420Z","cvss":{"score":2.7,"severity":"LOW","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"helm.sh/helm/v3","fixedVersion":"3.3.2"},{"ecosystem":"Go","name":"helm.sh/helm","fixedVersion":"2.16.11"}],"fix":{"url":"https://github.com/helm/helm/commit/055dd41cbe53ce131ab0357524a7f6729e6e40dc","label":"helm/helm@055dd41"},"references":[{"type":"ADVISORY","url":"https://github.com/helm/helm/security/advisories/GHSA-jm56-5h66-w453"},{"type":"FIX","url":"https://github.com/helm/helm/commit/055dd41cbe53ce131ab0357524a7f6729e6e40dc"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-09T10:21:09.702420Z"}}
