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."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"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"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":2.8,"impactScore":5.9}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-09T17:53:47.301776Z","id":"CVE-2026-55797","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-78"}]}],"references":[{"url":"https://github.com/argoproj/argo-cd/commit/1e3ddd0b7250aa23f489956b5fab8c13d0493a9f","source":"security-advisories@github.com"},{"url":"https://github.com/argoproj/argo-cd/commit/9b27aeb1a4fb15d11a0f01cad65dea1fdfc60205","source":"security-advisories@github.com"},{"url":"https://github.com/argoproj/argo-cd/pull/15864","source":"security-advisories@github.com"},{"url":"https://github.com/argoproj/argo-cd/releases/tag/v3.3.15","source":"security-advisories@github.com"},{"url":"https://github.com/argoproj/argo-cd/releases/tag/v3.4.10","source":"security-advisories@github.com"},{"url":"https://github.com/argoproj/argo-cd/releases/tag/v3.5.4","source":"security-advisories@github.com"},{"url":"https://github.com/argoproj/argo-cd/releases/tag/v3.6.0-rc2","source":"security-advisories@github.com"},{"url":"https://github.com/argoproj/argo-cd/security/advisories/GHSA-j6cw-g6p4-7hch","source":"security-advisories@github.com"}]}
