criticalC1Command InjectionMCP03-command-injectionAML.T0054
Pattern "`[^`]+`" matched in source_code: "`Client connected: ${socket.id}`" (at position 1264)
Replace exec()/execSync() with execFile() and pass arguments as an array, never as a string. Validate all inputs against an allowlist before use in any shell context. For subprocess.run, always pass a list and shell=False.
criticalJ2Git Argument InjectionMCP03-command-injectionAML.T0054
Pattern "--upload-pack|--receive-pack|--exec" matched in source_code: "--exec" (at position 4378)
Always terminate git argument lists with '--' before user-supplied paths. Never allow git_init on directories outside the configured workspace. Validate all git arguments against an allowlist. Block core.* config overrides in user-controlled inputs. See CVE-2025-68143/68144/68145 for the full attack chain.
criticalQ13MCP Bridge Package Supply Chain AttackMCP10-supply-chainAML.T0054
Pattern "["']@modelcontextprotocol/sdk["']\s*:\s*["'](?:\^|~|\*|latest)" matched in source_code: ""@modelcontextprotocol/sdk": "^" (at position 4659)
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.
highD1Known CVEs in DependenciesMCP08-dependency-vuln
Dependency "@modelcontextprotocol/sdk@1.7.0" has known CVEs:
Update dependencies to versions that patch known CVEs. Run 'npm audit fix' or 'pip-audit' to identify and resolve vulnerable dependencies.
highC7Wildcard CORSMCP07-insecure-config
Pattern "Access-Control-Allow-Origin.*\*" matched in source_code: "Access-Control-Allow-Origin', '*" (at position 771)
Replace wildcard CORS with an explicit allowlist of permitted origins. Wildcard CORS allows any website to make requests to the MCP server.
highD1Known CVEs in DependenciesMCP08-dependency-vuln
Dependency "express@4.18.2" has known CVEs:
Update dependencies to versions that patch known CVEs. Run 'npm audit fix' or 'pip-audit' to identify and resolve vulnerable dependencies.
highN3JSON-RPC Request ID CollisionMCP07-insecure-configAML.T0054
Pattern "(?:onMessage|on_message|handleResponse)\s*(?:=>|=|\()(?!.*(?:pendingRequests|pending_requests|requestMap|expected_id|id\s*===))" matched in source_code: "onMessage =" (at position 3252)
Use cryptographically random or UUID-based request IDs to prevent collision attacks. Do not use sequential integers — an attacker can predict the next ID and inject a response before the legitimate server responds (response spoofing). Validate that response IDs match pending request IDs. Reference: JSON-RPC 2.0 Section 4.1 — 'id' must be unique within a session.
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": "^9.0" (at position 4850)
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.
highN10Incomplete Handshake Denial of ServiceMCP07-insecure-configAML.T0054
Pattern "(?:createServer|listen)\s*\((?!.*(?:maxConnections|maxClients|connectionLimit|MAX_CONN))" matched in source_code: "createServer(" (at position 381)
Enforce a handshake timeout (recommended: 30 seconds) — terminate connections that do not complete the initialize handshake within the deadline. Limit maximum concurrent pending connections. An attacker can exhaust server connection slots by initiating MCP connections without completing the handshake (Slowloris-style attack). Reference: MCP spec 2025-03-26 lifecycle — initialize MUST complete before functional requests.
highN2JSON-RPC Notification FloodingMCP07-insecure-configAML.T0054
Pattern "(?:sendNotification|send_notification|notify|emit)\s*\((?!.*(?:queue|throttle|rateLimit|backpressure|bounded))" matched in source_code: "emit(" (at position 2755)
Implement bounded notification queues (recommended max size: 100 per subscription). Apply backpressure — when the queue is full, drop oldest notifications or pause the producer. Enforce per-client notification rate limits. JSON-RPC notifications have no response, so there is no natural flow control — servers MUST implement it explicitly.
mediumK17Missing Timeout or Circuit BreakerMCP07-insecure-configAML.T0054
Pattern "(?:fetch|axios|got|request|urllib|httpx|http\.get|http\.post)\s*\((?!.*(?:timeout|signal|AbortSignal|deadline|cancel))" matched in source_code: "Request(" (at position 1149)
Add timeouts to ALL external calls: HTTP requests (30s), database queries (10s), subprocess execution (60s), and MCP tool calls (30s). Implement circuit breakers that open after N consecutive failures (e.g., opossum, cockatiel). Use AbortSignal for cancellable operations. Required by EU AI Act Art. 15 and OWASP ASI08.
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.
