Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. Prior to 3.2.12, 3.3.10, and 3.4.2, Argo CD users with application write access can set link.argocd.argoproj.io/* annotations whose pipe-separated values are rendered by ui/src/app/applications/components/application-summary/application-summary.tsx in the Summary tab URLs section as anchor href values without URL validation, allowing javascript: execution in a higher-privileged user's authenticated Argo CD origin session. This issue is fixed in versions 3.2.12, 3.3.10, and 3.4.2.
