Overview

argocd-mcp is an Argo CD MCP Server

Affected versions of this package are vulnerable to Binding to an Unrestricted IP Address via the HTTP transport process. An attacker can gain unauthorized access to the full tool surface by sending unauthenticated requests to the listener, allowing them to create applications, request syncs, and modify resources using the operator's stored token. This is only exploitable if ARGOCD_API_TOKEN is configured.
