AI risk analysis

Summary: Argo CD's Kustomize integration allows command execution via crafted Git URLs with local transport (file://) that bypasses proper option separation, enabling attackers to execute arbitrary commands as the repo-server user when processing Kustomization manifests.
Exploitability: Exploitation is relatively straightforward for attackers with write access to Git repositories or the ability to upload files via POST /api/v1/applications/manifestsWithFiles endpoint, requiring only Application get permission on an existing Application.
Blast radius: The impact is critical as attackers can execute arbitrary commands with repo-server privileges, potentially accessing repository credentials and sensitive data, while the local transport does not require egress permissions to execute.
Detection: No reliable host or network indicator is derivable from the published description.
Prioritized remediation: Upgrade Argo CD to version 3.3.15, 3.4.10, 3.5.4, or 3.6.0-rc2 to fix the Kustomize option separator issue.

NVD description

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. From 2.7.0 until 3.3.15, 3.4.10, 3.5.4, and 3.6.0-rc2, Kustomize passes ref or version query values from remote resource, base, or component URLs to git fetch without an end-of-options separator. A leading-hyphen value can be parsed as --upload-pack and execute a command inside argocd-repo-server when the remote uses a local transport such as file://. Git does not run the supplied command for an https:// remote. The local transport does not leave the pod, so blocking repo-server egress does not prevent the execution. The command runs as the repo-server user, can read repository credentials and other process-accessible data, and can return output through manifest-generation errors. An attacker can commit a Kustomization to a Git repository that an Application builds or upload files through POST /api/v1/applications/manifestsWithFiles, also exposed by argocd app diff --local --server-side-generate. The upload path requires only Application get permission on an existing Application, without Application update or sync permission or repository write access. Kustomize 5.0.0 introduced acceptance of file://, whereas 4.5.7 rejects that transport; replacing the affected Kustomize with a newer version alone does not correct the missing option separator. This issue is fixed in versions 3.3.15, 3.4.10, 3.5.4, and 3.6.0-rc2.
