criticalQ13MCP Bridge Package Supply Chain AttackMCP10-supply-chainAML.T0054
Pattern "(?:mcp|fastmcp|langchain-mcp|llama-index-mcp)(?:>=|~=|==)?(?!\d)" matched in source_code: "fastmcp" (at position 33)
MCP bridge packages (mcp-remote, mcp-proxy, @modelcontextprotocol/sdk, fastmcp) are high-value supply chain targets — CVE-2025-6514 (CVSS 9.6) in mcp-remote affected 437,000+ installs. Always pin exact versions (no ^ or ~ ranges). Use lockfiles (package-lock.json, pnpm-lock.yaml, uv.lock). Never run `npx mcp-remote` without version pinning. Verify package integrity with `npm audit` or `pip-audit` before deployment. Reference: CVE-2025-6514, OWASP ASI04.

highC3Server-Side Request Forgery (SSRF)MCP04-data-exfiltrationAML.T0057
Pattern "\brequests\.(?:get|post|put|delete|patch|head|options|request)\s*\(\s*(?:req|request|input|param|params|args|url|uri|href|link|target|destination|endpoint|host|address|resource|src|source)" matched in source_code: "requests.post(url" (at position 11362)
Validate ALL user-supplied URLs before making HTTP requests: 1. Parse the URL and check the hostname against an explicit allowlist of permitted domains. 2. Block requests to RFC 1918 private ranges: 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16. 3. Block loopback (127.0.0.0/8), link-local (169.254.0.0/16), and IPv6 equivalents. 4. Block file:// and other non-http(s) protocols explicitly. 5. Disable automatic redirect following, or re-validate each redirect destination. 6. In cloud environments: block requests to IMDS endpoints (169.254.169.254, metadata.google.internal) at both the application AND network layer. Example (Node.js): Use the `ssrf-req-filter` package or implement URL validation against an allowlist before calling fetch/axios/got.
