From 2.11.0 until 3.3.15, 3.4.10, 3.5.4, and 3.6.0-rc2, the Argo CD repo-server is vulnerable to command injection when it clones, tests, or fetches an SSH Git repository configured with a proxy URL. The proxy host and port are embedded in an SSH ProxyCommand that is executed through a shell without neutralizing shell metacharacters. A user who can create or update a repository or repository credential template can supply a crafted proxy host to execute commands in the repo-server and access its Git, Helm, and OCI credentials. This issue is fixed in versions 3.3.15, 3.4.10, 3.5.4, and 3.6.0-rc2.","provenance":"source","from":"CVE.org"},"cvss":{"score":8.8,"severity":"HIGH","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","provenance":"source","from":"CVE.org CNA"},"epss":{"score":0.01869,"percentile":0.79245,"provenance":"source"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"references":[{"url":"https://github.com/argoproj/argo-cd/security/advisories/GHSA-j6cw-g6p4-7hch","tags":["x_refsource_CONFIRM"]},{"url":"https://github.com/argoproj/argo-cd/pull/15864","tags":["x_refsource_MISC"]},{"url":"https://github.com/argoproj/argo-cd/commit/1e3ddd0b7250aa23f489956b5fab8c13d0493a9f","tags":["x_refsource_MISC"]},{"url":"https://github.com/argoproj/argo-cd/commit/9b27aeb1a4fb15d11a0f01cad65dea1fdfc60205","tags":["x_refsource_MISC"]},{"url":"https://github.com/argoproj/argo-cd/releases/tag/v3.3.15","tags":["x_refsource_MISC"]},{"url":"https://github.com/argoproj/argo-cd/releases/tag/v3.4.10","tags":["x_refsource_MISC"]},{"url":"https://github.com/argoproj/argo-cd/releases/tag/v3.5.4","tags":["x_refsource_MISC"]},{"url":"https://github.com/argoproj/argo-cd/releases/tag/v3.6.0-rc2","tags":["x_refsource_MISC"]}],"priority":{"score":22.0,"factors":[{"name":"EPSS percentile","points":15.85},{"name":"CVSS severity","points":6.16}]},"vendorSlug":"argoproj","affectedVersions":[{"vendor":"argoproj","product":"argo-cd","versions":[">= 2.11.0, <= 2.14.21",">= 3.0.0, < 3.3.15",">= 3.4.0, < 3.4.10",">= 3.5.0, < 3.5.4","= 3.6.0-rc1"]}],"affected":[{"ecosystem":"Go","package":"github.com/argoproj/argo-cd/v2","vulnerableRanges":[">=2.11.0, <=2.14.21",">=2.11.0"],"patched":[],"from":["GHSA-j6cw-g6p4-7hch","GO-2026-6701"],"provenance":"source"},{"ecosystem":"Go","package":"github.com/argoproj/argo-cd/v3","vulnerableRanges":[">=3.0.0, <3.3.15",">=3.4.0, <3.4.10",">=3.5.0, <3.5.4",">=3.6.0-rc1, <3.6.0-rc2"],"patched":["3.3.15","3.4.10","3.5.4","3.6.0-rc2"],"from":["GHSA-j6cw-g6p4-7hch","GO-2026-6701"],"provenance":"source"},{"ecosystem":"Go","package":"github.com/argoproj/argo-cd","vulnerableRanges":["all versions"],"patched":[],"from":["GO-2026-6701"],"provenance":"source"}],"euvd":{"id":"EUVD-2026-95912","exploited":false,"provenance":"source"},"lineage":{"familyId":"fam-argoproj-argo-cd-cve-2026-55797","children":[{"from":"CVE-2026-55797","to":"CVE-2026-113708","relation":"related","confidence":"high","kind":"lineage","evidence":[{"kind":"osv-related","provenance":"source","id":"GHSA-j6cw-g6p4-7hch","via":"related"}]},{"from":"CVE-2026-55797","to":"CVE-2026-113709","relation":"related","confidence":"high","kind":"lineage","evidence":[{"kind":"osv-related","provenance":"source","id":"GHSA-j6cw-g6p4-7hch","via":"related"}]}],"packageHistory":[{"cve":"CVE-2026-43824","published":"2026-05-02","fixed":"3.3.9","kev":false},{"cve":"CVE-2026-45737","published":"2026-07-15","fixed":"3.4.2","kev":false},{"cve":"CVE-2026-45738","published":"2026-07-15","fixed":"3.4.2","kev":false,"link":{"from":"CVE-2026-45738","to":"CVE-2026-55797","relation":"successor","confidence":"low","kind":"sequence","evidence":[{"kind":"version-step","provenance":"source","package":"Go:github.com/argoproj/argo-cd/v3","fromFixed":"3.3.10","toFixed":"3.3.15","daysApart":86}]}},{"cve":"CVE-2026-55797","published":"2026-10-09","fixed":"3.6.0-rc2","kev":false},{"cve":"CVE-2026-77459","published":"2026-10-13","fixed":"3.6.0-rc2","kev":false}],"package":"Go:github.com/argoproj/argo-cd/v3"}}
