Today's Oil Price - 今日油价

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward oil-price lookup that uses the user's JisuAPI key to call the documented Jisu oil API.

Install this only if you have or plan to use a JisuAPI account and are comfortable sending your JISU_API_KEY and oil-price query parameters to api.jisuapi.com. No hidden persistence or unrelated data access was found.

A.I.G

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.

Content

No source excerpt is available for this finding.

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
93% confidence
Finding

The skill declares runtime requirements that imply access to environment variables and outbound network use, but it does not explicitly declare a tool/permission scope. This weakens least-privilege controls and transparency, making it easier for a skill execution environment to grant broader capabilities than reviewers or users expect.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The natural-language content of the skill, including its description, usage guidance, and examples, is entirely in Chinese. Under the policy rule, forcing a specific language without giving the user a choice can be a locale/language policy violation unless the constraint is explicitly justified.

External Transmission

Medium
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.
