{"id":"CVE-2026-55797","state":"PUBLISHED","title":"Argo CD repo-server command injection via crafted SSH repository SOCKS5 proxy URL","description":"Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. 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.","publishedAt":"2026-10-09T16:43:35.954Z","updatedAt":"2026-10-09T17:53:53.357Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["argoproj argo-cd"],"affected":[{"vendor":"argoproj","product":"argo-cd","versions":[{"version":">= 2.11.0, <= 2.14.21","status":"affected"},{"version":">= 3.0.0, < 3.3.15","status":"affected"},{"version":">= 3.4.0, < 3.4.10","status":"affected"},{"version":">= 3.5.0, < 3.5.4","status":"affected"},{"version":"= 3.6.0-rc1","status":"affected"}]}],"references":["https://github.com/argoproj/argo-cd/security/advisories/GHSA-j6cw-g6p4-7hch","https://github.com/argoproj/argo-cd/pull/15864","https://github.com/argoproj/argo-cd/commit/1e3ddd0b7250aa23f489956b5fab8c13d0493a9f","https://github.com/argoproj/argo-cd/commit/9b27aeb1a4fb15d11a0f01cad65dea1fdfc60205","https://github.com/argoproj/argo-cd/releases/tag/v3.3.15","https://github.com/argoproj/argo-cd/releases/tag/v3.4.10","https://github.com/argoproj/argo-cd/releases/tag/v3.5.4","https://github.com/argoproj/argo-cd/releases/tag/v3.6.0-rc2"],"weaknesses":["CWE-78"],"ingestedAt":"2026-10-29T20:12:24.861Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/55xxx/CVE-2026-55797.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-55797","state":"PUBLISHED","datePublished":"2026-10-09T16:43:35.954Z","dateUpdated":"2026-10-09T17:53:53.357Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-17T14:40:28.381Z"},"containers":{"cna":{"title":"Argo CD repo-server command injection via crafted SSH repository SOCKS5 proxy URL","descriptions":[{"lang":"en","value":"Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes.
