criticalQ13MCP Bridge Package Supply Chain AttackMCP10-supply-chainAML.T0054
Pattern "(?:mcp|fastmcp|langchain-mcp|llama-index-mcp)(?:>=|~=|==)?(?!\d)" matched in source_code: "MCP" (at position 51)
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 "\.(?:get|post|put|delete|patch|request)\s*\([^)]*(?:url|uri|target|endpoint|host)[^)]*(?:req|input|param|args|f['"]|\+)" matched in source_code: ".get(url, params=param" (at position 1395)
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.

highN7Progress Token Prediction and InjectionMCP07-insecure-configAML.T0054
Pattern "(?:total|progressTotal|progress_total)\s*[:=]\s*(?:params|request|body|data)\s*\." matched in source_code: "total = body." (at position 5712)
Use unpredictable progress tokens (UUIDs or cryptographic random values). Validate that progress notification recipients match the original request sender. Do not accept progress tokens from untrusted input — a malicious server could inject fake progress notifications to manipulate client UI state or create timing side channels. Reference: MCP spec 2025-03-26 Section 5.1 (Progress).
