Aliyun Search 1.0.0
Security checks for vulnerabilities and agentic risk
Overview
This skill is a straightforward Alibaba Cloud search helper with disclosed credential and network requirements, though users should install its dependencies carefully.
Before installing, use a virtual environment, pin reviewed dependency versions, remove the unused requests dependency if possible, and provide Alibaba Cloud keys with only the permissions needed for UnifiedSearch. Expect search queries and optional location parameters to be sent to Alibaba Cloud.
Vulnerability Patterns
- Insecure DependenciesIntroduces malicious components through unsafe dependency sources
- 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

Undeclared Tool Scope
Medium
- Category
- MCP Least Privilege
- Confidence
- 93% confidence
- Finding
The skill documentation indicates capabilities involving environment variables and outbound network access, but it does not declare any explicit tool scope such as permissions or allowed-tools. That creates a mismatch between what the skill can do and what a reviewer or runtime policy may expect, increasing the risk of unintended secret access or unsanctioned external communication.

Natural-Language Policy Violations

- Not specified by scanner
- Confidence
- 91% confidence
- Finding
This code file contains natural-language docstrings and output strings exclusively in Chinese, including the module description and function documentation. Under the stated policy, forcing a specific language without user opt-in is a locale/language policy violation.
