Prior to @contentful\/mcp-server 1.7.19 and @contentful\/mcp-tools 0.4.5, export_space and import_space in packages\/mcp-tools\/src\/tools\/jobs\/space-to-space-migration\/exportSpace.ts and packages\/mcp-tools\/src\/tools\/jobs\/space-to-space-migration\/importSpace.ts expose host, proxy, rawProxy, and insecure network options to LLM-controlled tool arguments and combine those options with the server&#8217;s CONTENTFUL_MANAGEMENT_TOKEN. After space_to_space_migration_handler enables the migration tools, a direct MCP call or prompt injection through attacker-controlled Contentful content can redirect Contentful Management API requests and their Authorization header to an attacker-controlled host or proxy. The regular tools that use createToolClient are unaffected because those tools pin the host from server configuration. Exposure of the personal access token permits persistent out-of-band access to every Contentful space within the token&#8217;s scope.
