企业工商信息查询 - Enterprise Business Information Inquiry

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward JisuAPI company-record lookup helper, with expected external API use and no evidence of hidden execution, persistence, or destructive behavior.

Install only if you are comfortable using JisuAPI for these lookups. Treat company names, registration numbers, credit codes, and organization codes as data that will be sent to JisuAPI along with your API key, and avoid using it for confidential investigations unless your organization allows that provider.

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

High
Category
MCP Tool Poisoning
Confidence
85% confidence
Finding

Mixing characters from multiple Unicode scripts in a single identifier is a common technique to create visually ambiguous tool names.

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
95% confidence
Finding

The skill declares that it needs an environment variable and, by design, invokes a third-party API over the network, but it does not declare an explicit tool/permission scope. This creates a governance gap: an agent or platform may allow broader execution than users expect, reducing transparency and weakening least-privilege controls for network and secret access.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The trigger text includes broad language such as '或类似工商信息问题时' ('or similar business-registration information questions'), which can cause the skill to activate for loosely related prompts. Over-broad invocation increases the chance of unnecessary third-party data transmission and unintended API usage or charges.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The skill documentation explains how to query company data through JisuAPI but does not clearly warn users that supplied company names, registration numbers, or credit codes will be sent to an external third-party service. This lack of disclosure can lead to privacy, confidentiality, and compliance issues, especially for sensitive or non-public business investigations.

External Transmission

Medium
Category
Data Exfiltration
Confidence
86% confidence
Finding

The code is explicitly designed to communicate with an external HTTPS API, so there is an intentional external transmission channel. While HTTPS reduces interception risk, the security concern is that user-supplied business query data and the API key are used in outbound requests to a third party, which creates privacy, compliance, and data-handling exposure if users are not informed.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The skill sends user-provided company identifiers and search terms directly to a third-party API, which is a real data disclosure boundary. In this business-information context the transmitted data may still be sensitive from a user privacy or enterprise confidentiality standpoint, and the skill provides no warning, consent step, or minimization before sending it off-platform.
