CKAN MCP Server: Information disclosure via verbose error reflection

The CKAN MCP Server (@aborruso/ckan-mcp-server) reflects raw upstream response bodies and internal exception messages to callers instead of sanitized messages, disclosing sensitive information like hostnames, internal IPs, and database errors. This vulnerability amplifies SSRF attacks by providing a response-content channel to internal endpoints.
