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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-55797)\n\nAffected packages:\n\n- `github.com/argoproj/argo-cd/v2 >= 2.11.0, <= 2.14.21`\n- `github.com/argoproj/argo-cd/v3 >= 3.0.0, < 3.3.15`\n- `github.com/argoproj/argo-cd/v3 >= 3.4.0, < 3.4.10`\n- `github.com/argoproj/argo-cd/v3 >= 3.5.0, < 3.5.4`\n- `github.com/argoproj/argo-cd/v3 = 3.6.0-rc1`\n\nPatched in:\n\n- `github.com/argoproj/argo-cd/v3 3.3.15`\n- `github.com/argoproj/argo-cd/v3 3.4.10`\n- `github.com/argoproj/argo-cd/v3 3.5.4`\n- `github.com/argoproj/argo-cd/v3 3.6.0-rc2`\n\nSource: https://github.com/advisories/GHSA-j6cw-g6p4-7hch","depth":"twilight","depthScore":48,"depthScoreParts":{"impact":48.4,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
