Summary

argoproj-labs argocd-mcp through 0.9.0 contains a path traversal flaw (CWE-22) in its delete_application tool. The tool does not validate applicationName values, so dot-segment input can redirect requests to unintended Argo CD API endpoints. A remote user with low privileges, including a prompt-injected model acting for an MCP client, can send authenticated DELETE requests that remove repositories, clusters or projects within the token's RBAC permissions.

Description from the CNA

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.
