Users should update to this version as soon as possible.\n\n## Workarounds\n\nEnsure that any configured `credsStore` or `credHelpers` entries in the configuration file reference an installed credential helper that is executable and on the `PATH`.\n\n## For more information\n\nIf you have any questions or comments about this advisory:\n\n* [Open an issue](https://github.com/docker/cli/issues/new/choose)\n* Email us at security@docker.com if you think you’ve found a security bug","published":"2021-10-04T20:15:07.757Z","modified":"2026-07-08T06:27:06.058626279Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":{"score":0.01652,"percentile":0.75381,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/docker/cli","fixedVersion":"20.10.9"}],"fix":{"url":"https://github.com/docker/cli/commit/893e52cf4ba4b048d72e99748e0f86b2767c6c6b","label":"docker/cli@893e52c"},"references":[{"type":"WEB","url":"https://cert-portal.siemens.com/productcert/pdf/ssa-222547.pdf"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/B5Q6G6I4W5COQE25QMC7FJY3I3PAYFBB/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ZNFADTCHHYWVM6W4NJ6CB4FNFM2VMBIB/"},{"type":"ADVISORY","url":"https://github.com/docker/cli/security/advisories/GHSA-99pg-grm5-qq3v"},{"type":"FIX","url":"https://github.com/docker/cli/commit/893e52cf4ba4b048d72e99748e0f86b2767c6c6b"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-41092"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/B5Q6G6I4W5COQE25QMC7FJY3I3PAYFBB"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/ZNFADTCHHYWVM6W4NJ6CB4FNFM2VMBIB"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-08T06:27:06.058626279Z"}}
