This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.

01 / Meaning

Why it matters

Published affected context helps an owner decide what evidence to gather. This report has not examined your application.

CVSS

8.8 high

source listed
  • >= 2.11.0, <= 2.14.21

### Impact Argo CD runs a shell command in the repo-server when it clones or fetches an SSH Git repository that has a proxy URL. The proxy host and port are copied into an SSH `ProxyCommand`. A host that contains shell metacharacters breaks out of that command and runs in the repo-server. All versions from v2.11.0 onward are affected, including every currently supported release. v2.10.20 and earlier are not. The behavior was introduced in 9b27aeb1a4 (2024-01-09, #15864), the change that added SOCKS5 proxy support for SSH Git URLs, and was first released in v2.11.0. The repository must use SSH. `http`, `https`, and `socks5` proxy URLs all take this path when they are set on an SSH repository. An HTTPS Git repository uses the proxy as an HTTP proxy and does not build this command. Anyone who can create or update a repository or a repository credential template can set the proxy. That includes a project-scoped repository permission, `argocd repo add --proxy`, and a repository Secret. A credential template applies its proxy to every matching SSH r

03 / Response

What to do next

  1. investigate

    Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.

    Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database

A fixed release is not deployment evidence.

Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
