Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed QuoteNode market-data REST helper that sends user-provided requests and an API key to allowlisted datatk HTTPS endpoints.

Install only if you intend to use QuoteNode/dataTrack market-data APIs. Keep env.json private, use a trusted datatk endpoint, and avoid placing unrelated sensitive data in request bodies because the script sends the body and API key to the configured service.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
96% confidence
Finding

The skill explicitly instructs users to invoke a network-enabled script and send requests to external endpoints, but the manifest declares no tool scope such as permissions or allowed-tools. This creates a mismatch between declared and actual capabilities, reducing transparency and policy enforcement and increasing the risk of unintended or unauthorized outbound network access with user-supplied credentials.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
88% confidence
Finding

This code performs a network request that sends user-supplied JSON and an API key to a remote endpoint, which is a safety-relevant operation under the code-file warning criteria. While the script validates the endpoint and prints errors on failure, it does not provide a user-facing disclosure or confirmation before transmitting the data, and there is no nearby comment or docstring explaining that this action sends data externally.
