期货查询 - Futures Inquiry

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward futures-market lookup tool that uses a disclosed JisuAPI key and external API calls for its stated purpose.

Install only if you are comfortable using JisuAPI for futures data. The skill needs your JISU_API_KEY and will send that key plus requested exchange, contract, and date-range parameters to JisuAPI over the network; it does not appear to modify local files, accounts, or trading data.

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
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

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
89% confidence
Finding

The skill declares runtime requirements that imply access to an environment variable and outbound network use, but it does not declare an explicit tool/permission scope. This creates a transparency and governance gap: a host may permit broader execution than users or reviewers expect, especially since the skill sends requests to a third-party API using a secret key.

External Transmission

Category
Data Exfiltration
Confidence
60% confidence
Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
79% confidence
Finding

The skill name and invocation guidance are entirely Chinese-focused and tell the agent to use the skill when the user says Chinese phrases, but they do not state that the skill is China-market-specific or offer any language/locale choice. Under the policy, a forced language or locale without opt-in can be a natural-language policy issue unless clearly justified.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
93% confidence
Finding

The skill documentation identifies a third-party data provider but does not clearly warn that user-supplied contract codes, market selections, and date ranges will be transmitted externally. This is a privacy/transparency issue because users may not realize their queries are leaving the local environment and being shared with JisuAPI.
