Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed hot-search lookup tool that calls JisuAPI using a user-provided API key and does not show hidden persistence, credential theft, or unrelated behavior.

Before installing, users should understand that hot-search lookups contact JisuAPI and require their JISU_API_KEY. This appears purpose-aligned, but users should treat the API key like a credential and review JisuAPI's terms, pricing, and privacy practices.

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

  • MCP Least PrivilegeUnderdeclared Capability, Wildcard Permission, Missing Permission Declaration

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.

Lp3

Medium
Category
MCP Least Privilege
Confidence
88% confidence
Finding
The skill declares executable and network-dependent behavior via python3 and an API key, but it does not define an explicit tool/permission scope. That can lead to overbroad execution in agent environments where users and reviewers cannot clearly see that environment access and outbound requests are required.

Vague Triggers

Medium
Confidence
91% confidence
Finding
The trigger phrase 'or similar hot-search list questions' is overly broad, which can cause the agent to invoke this skill for loosely related requests. Because the skill performs external API calls, ambiguous triggering increases the chance of unnecessary data disclosure to a third party and unintended tool use.

Missing User Warnings

Medium
Confidence
91% confidence
Finding
The skill description does not clearly warn that user queries will be sent to an external third-party API service. This reduces transparency and can expose user-provided query context or usage patterns to the provider without informed consent.

External Transmission

Medium
Category
Data Exfiltration
Content
import requests


BASE_URL = "https://api.jisuapi.com/hotsearch"


def _call_hotsearch(path: str, appkey: str):
Confidence
60% confidence
Finding
Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
