US Business Registry Open Data

Security checks for vulnerabilities and agentic risk

Overview

This skill coherently helps users download public US business-registry data from documented government open-data APIs, with no evidence of hidden execution, credential theft, persistence, or destructive behavior.

Before installing, expect this skill to contact government open-data portals and to create potentially large local JSONL files. Use a Socrata app token only for Socrata rate limits, choose an output directory intentionally, and re-check dataset licenses if enabling any deferred source.

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
Vulnerability Patterns
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • MCP Least PrivilegeUnderdeclared Capability, Wildcard Permission, Missing Permission Declaration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
85% confidence
Finding

The skill advertises executable/network-capable behavior by instructing the agent to run a bundled Python fetcher and make live API requests, but it does not declare any explicit tool scope or permissions. That ambiguity can cause an orchestrator to grant broader-than-necessary access or let the skill run in environments where network and environment access were not clearly approved, increasing the chance of unintended outbound requests or secret exposure through inherited runtime context.
