description

Red Hat OpenShift GitOps deployments using Argo CD Image Updater are affected by command injection when processing a proxy URL for an SSH Git repository. An attacker who can set that proxy value may execute commands and access credentials with the Image Updater process permissions.

mitigation

Restrict who can create or modify SSH Git repository proxy settings, and review existing proxy URL configuration for untrusted values. Limit Image Updater process permissions and credential access until an updated package is available.
