Unauthenticated internal service access via unrestricted proxy URL
Published Aug 9, 2026 · Updated Aug 9, 2026
Server-side request forgery in adafap API-MCP allows remote attackers to make HTTP requests from the server via POST /api/proxy. The route accepts a caller-controlled absolute URL, assigns it directly to the Axios target, follows redirects, and applies no destination allowlist or private-network check. No authentication or user interaction is required; reachable callers can access loopback, private-network, metadata, or attacker-controlled HTTP endpoints from the server's network position.
