criticalQ13MCP Bridge Package Supply Chain AttackMCP10-supply-chainAML.T0054
Pattern "["']@modelcontextprotocol/sdk["']\s*:\s*["'](?:\^|~|\*|latest)" matched in source_code: ""@modelcontextprotocol/sdk": "^" (at position 1019)
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.

highK19Missing Runtime Sandbox EnforcementMCP07-insecure-configAML.T0054
Pattern "(run[_\s-]?as[_\s-]?root|EUID.*0|uid.*0)(?!.*(?:drop|setuid|seteuid|change.?user))" matched in source_code: "uid": "^13.0.0" (at position 1696)
Run MCP servers in sandboxed containers with: (1) No --privileged flag, (2) Minimal Linux capabilities (drop ALL, add only needed), (3) Read-only root filesystem, (4) Non-root user, (5) Seccomp/AppArmor profiles enabled, (6) No host mounts except data volumes. CoSAI warns containers alone are insufficient — add seccomp profiles. Required by CoSAI MCP-T8 and ISO 27001 A.8.22.
