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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-78"],"references":["https://github.com/argoproj/argo-cd/commit/1e3ddd0b7250aa23f489956b5fab8c13d0493a9f","https://github.com/argoproj/argo-cd/commit/9b27aeb1a4fb15d11a0f01cad65dea1fdfc60205","https://github.com/argoproj/argo-cd/pull/15864","https://github.com/argoproj/argo-cd/releases/tag/v3.3.15","https://github.com/argoproj/argo-cd/releases/tag/v3.4.10"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-55797","score":0.01869,"percentile":0.79183,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-j6cw-g6p4-7hch","url":"https://osv.dev/vulnerability/GHSA-j6cw-g6p4-7hch","summary":"Argo CD repo-server command injection via crafted SSH repository SOCKS5 proxy URL","modified":"2026-10-21T03:11:56.486094067Z","packages":[{"ecosystem":"Go","name":"github.com/argoproj/argo-cd/v2","purl":"pkg:golang/github.com/argoproj/argo-cd/v2","ranges":[">=2.11.0 <=2.14.21"],"fixed":[]},{"ecosystem":"Go","name":"github.com/argoproj/argo-cd/v3","purl":"pkg:golang/github.com/argoproj/argo-cd/v3","ranges":[">=3.0.0 <3.3.15"],"fixed":["3.3.15"]},{"ecosystem":"Go","name":"github.com/argoproj/argo-cd/v3","purl":"pkg:golang/github.com/argoproj/argo-cd/v3","ranges":[">=3.4.0 <3.4.10"],"fixed":["3.4.10"]},{"ecosystem":"Go","name":"github.com/argoproj/argo-cd/v3","purl":"pkg:golang/github.com/argoproj/argo-cd/v3","ranges":[">=3.5.0 <3.5.4"],"fixed":["3.5.4"]},{"ecosystem":"Go","name":"github.com/argoproj/argo-cd/v3","purl":"pkg:golang/github.com/argoproj/argo-cd/v3","ranges":[">=3.6.0-rc1 <3.6.0-rc2"],"fixed":["3.6.0-rc2"]}]},{"id":"GO-2026-6701","url":"https://osv.dev/vulnerability/GO-2026-6701","summary":"Argo CD repo-server command injection via crafted SSH repository SOCKS5 proxy URL in github.com/argoproj/argo-cd","modified":"2026-10-19T21:40:54.044086655Z","packages":[{"ecosystem":"Go","name":"github.com/argoproj/argo-cd","purl":"pkg:golang/github.com/argoproj/argo-cd","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/argoproj/argo-cd/v2","purl":"pkg:golang/github.com/argoproj/argo-cd/v2","ranges":[">=2.11.0"],"fixed":[]},{"ecosystem":"Go","name":"github.com/argoproj/argo-cd/v3","purl":"pkg:golang/github.com/argoproj/argo-cd/v3","ranges":[">=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"],"fixed":["3.3.15","3.4.10","3.5.4","3.6.0-rc2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
