What it is

argocd-mcp (Argo CD MCP Server) through 0.9.0 contains a path traversal vulnerability in the delete_application tool that allows MCP clients to reach unintended API endpoints via unvalidated applicationName values. Attackers or prompt-injected models can supply dot-segment values like ../repositories/ to send authenticated DELETE requests deleting repositories, clusters, or projects within the token's RBAC permissions.
