criticalC1Command InjectionMCP03-command-injectionAML.T0054
Pattern "eval\s*\(" matched in source_code: "EVAL (" (at position 30514)
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.
criticalN15JSON-RPC Method Name ConfusionMCP05-privilege-escalationAML.T0054
Pattern "(?:eval|Function|exec)\s*\(.*(?:method|action|procedure)" matched in source_code: "EVAL (with offset): Provide docId + offset (+ optional maxLength, default 3000). Returns text centered around the offset position, extracting approximately 1,500 chars before and 1,500 chars after the offset. Finds natural paragraph boundaries for clean extraction.\n\n2. SEQUENTIAL READING (with maxLength, no offset): Provide docId + maxLength (no offset). Returns first maxLength characters from document start. Includes nextOffset for pagination to continue reading.\n\n3. FULL DOCUMENT RETRIEVAL (no offset, no maxLength): Provide docId only. Returns complete document text (may be 100KB+). Note: May use significant context window space.\n\nPARAMETERS:\n- docId: Document ID to retrieve (required)\n- offset (optional): Character position to center extraction" (at position 30514)
Validate all JSON-RPC method names against an explicit allowlist. Do not use dynamic dispatch (obj[method]()) for method routing — an attacker can invoke internal methods not intended for external access. Separate tool invocation (tools/call) from protocol methods (initialize, ping). Validate that tools/call only dispatches to registered tool names. Reference: JSON-RPC 2.0 Section 4.1, CWE-749 (Exposed Dangerous Method).
criticalQ11Code Suggestion Poisoning via MCPMCP01-prompt-injectionAML.T0054.001
Pattern "(?:suggest|generate|complete|insert).*(?:code|function|class|import|require)" matched in source_code: "complete document text (may be 100KB+). Note: May use significant context window space.\n\nPARAMETERS:\n- docId: Document ID to retrieve (require" (at position 31070)
MCP tool outputs flowing into IDE code suggestion contexts must be sanitized. Implement output content policies that: (1) strip hidden Unicode characters (zero-width, RTL override, tag characters), (2) detect embedded instructions targeting AI code assistants, (3) validate code blocks against security patterns before they enter the suggestion pipeline, (4) never include shell commands in tool outputs without explicit [COMMAND] markers visible to the user. Reference: IDEsaster (Dec 2025), arXiv 2509.22040.
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 61)
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.
criticalQ9Agentic Workflow DAG ManipulationMCP05-privilege-escalationAML.T0058
Pattern "(?:next[_\s]?(?:step|node|agent)|route[_\s]?to|redirect[_\s]?to|skip[_\s]?(?:step|node|validation))" matched in source_code: "nextStep" (at position 44919)
MCP tools must NOT modify agentic workflow graphs, execution order, or routing during runtime. Workflow structure should be immutable once execution begins. If dynamic workflow modification is required, implement: (1) approval gates that require human confirmation before graph mutations, (2) integrity checks that validate the workflow graph against a known-good baseline after each step, (3) audit logging of all graph modifications with rollback capability. Reference: arXiv 2602.19555, Trend Micro subgraph impersonation attack (2026).
highK13Unsanitized Tool OutputMCP02-tool-poisoningAML.T0054
Pattern "(?:fetch|axios|requests?\.get|http\.get).*(?:return|respond|result|body|text|data)(?!.*(?:sanitize|escape|encode|strip|validate|parse|extract))" matched in source_code: "fetching voting result" (at position 26278)
Sanitize all external data before including in tool responses. Implement output encoding that neutralizes prompt injection patterns. Truncate excessively long content. Validate structure before passing database results. Apply the principle: treat all external data as untrusted, even in tool outputs. Required by CoSAI MCP-T4.
highK18Cross-Trust-Boundary Data Flow in Tool ResponseMCP04-data-exfiltrationAML.T0054
Pattern "(?:ssn|social[_\s-]?security|credit[_\s-]?card|bank[_\s-]?account|medical|health).*(?:return|respond|send|post|emit)" matched in source_code: "healthcare, or finance. This tool takes no parameters as it return" (at position 17242)
Implement data flow taint tracking: tag data from sensitive sources (databases, credentials, files) and prevent it from flowing to external sinks (HTTP, webhooks, email) without explicit sanitization/redaction. Apply data classification and enforce boundary controls per trust level. Required by ISO 27001 A.5.14 and CoSAI MCP-T5.
