NVD 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.

    🚨HIGH - Argo CD repo-server SSH ProxyCommand OS Command Injection (CVE-2026-55797) Argo CD repo-server builds an ssh ProxyCommand from the repo proxy URL when cloning/testing/fetching SSH Git repos; proxy host/port are shell-interpreted without metacharacter neutralization, enabling command injection by users who can create/update repos or credential templates. Impact: RCE in repo-server context + access to stored Git/Helm/OCI creds. 👉Affected: Argo CD repo-server (http://github.com/argoproj/argo-cd/v2, v3) < 3.3.15 / 3.4.10 / 3.5.4 / 3.6.0-rc2 | Upgrade to 3.3.15 / 3.4.10 / 3.5.4 / 3.6.0-rc2
