CyberRota Analysis
AI-GeneratedThe Contentful MCP Server is vulnerable due to improper handling of host and proxy options in its space migration tools, allowing attackers to exploit prompt injection vulnerabilities. This can lead to unauthorized access to the Contentful Management API, potentially exposing sensitive personal access tokens and enabling persistent access to affected spaces. Organizations using the affected versions of the MCP Server and migration tools should prioritize upgrading to the patched versions to mitigate this high-severity risk.

Original NVD Description
Contentful MCP Server is a Model Context Protocol server for the Contentful Management API. 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'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's scope. This issue is fixed in @contentful/mcp-server 1.7.19 and @contentful/mcp-tools 0.4.5.
