Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward Chinese news lookup wrapper that uses a disclosed JisuAPI key and network calls for its stated purpose.

Before installing, users should understand that news requests and the JISU_API_KEY are sent to JisuAPI, so they should only use an app key they are comfortable using with that third-party service. The skill otherwise appears narrowly scoped to fetching news and channel lists.

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.

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
86% confidence
Finding

The skill declares it needs environment access and implicitly performs network calls via the referenced Python script and external API, but the manifest does not define an explicit tool scope such as permissions or allowed-tools. This weakens least-privilege controls and can let the runtime grant broader capabilities than reviewers or users expect.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
86% confidence
Finding

The activation description and example utterances are entirely in Chinese and implicitly assume Chinese-language user requests. Under the policy, locale or language constraints should either be optional, user-selected, or clearly documented as region-specific; this file does not provide such an opt-in or justification.

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
89% confidence
Finding

This code includes natural-language descriptions, comments, and usage examples in Chinese without offering an alternative language or indicating that the skill is region- or language-specific. Under the language/locale policy, forcing a specific language in user-facing text without opt-in is a policy concern.
