criticalK8Cross-Boundary Credential SharingMCP05-privilege-escalationAML.T0054
Pattern "(return|respond|output|result).*(?:token|credential|api[_\s-]?key|secret|password|bearer)" matched in source_code: "Returns a ZIP with FINC01 application, FINC02 secret" (at position 2043)
Never forward, share, or embed credentials across trust boundaries. Use OAuth token exchange (RFC 8693) to create scoped, delegated tokens instead of passing original credentials. Never include credentials in tool responses. Required by ISO 27001 A.5.17 and OWASP ASI03.
criticalQ13MCP Bridge Package Supply Chain AttackMCP10-supply-chainAML.T0054
Pattern "["']@modelcontextprotocol/sdk["']\s*:\s*["'](?:\^|~|\*|latest)" matched in source_code: ""@modelcontextprotocol/sdk": "^" (at position 3412)
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: "uide. Optionally includes FDMS0" (at position 1805)
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.

lowF4MCP Spec Non-ComplianceMCP07-insecure-config
Server fails MCP spec compliance checks: required:server_name; required:server_version; required:protocol_version; recommended:tool_descriptions; recommended:parameter_descriptions
Follow the MCP specification for server metadata. Include server name, version, and protocol version. Provide descriptions for all tools and parameters.
