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.
