Security audit

Alibaba Cloud Docs + API Reviewer

Security checks for vulnerabilities and agentic risk

Overview

The skill mostly performs a legitimate Alibaba Cloud documentation review, but it unnecessarily tells users to configure cloud credentials that the included script does not use.

Review this skill before installing if you would run it in an environment containing Alibaba Cloud credentials. The script itself appears to fetch public Alibaba Cloud documentation and write local reports, but the skill instructions should not require cloud access keys unless a future authenticated, read-only use case is clearly documented and scoped.

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

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
89% confidence
Finding

The skill instructs the agent to run a Python script that performs network access and writes artifacts to disk, but the manifest does not declare any tool restrictions such as allowed-tools or permissions. This creates a least-privilege and governance gap: an agent/runtime may grant broader capabilities than necessary, making unintended network access or file writes harder to constrain and audit.

Intent-Code Divergence

Medium

Not specified by scanner
Confidence
90% confidence
Finding

The prerequisites request Alibaba Cloud credentials and mention 'mutating operations' even though the described workflow is limited to reviewing public product and OpenAPI documentation. This can unnecessarily prompt users or agents to load sensitive cloud credentials into the environment, increasing the risk of credential exposure or accidental authenticated/API-modifying use that is unrelated to the task.

Natural-Language Policy Violations

Confidence
93% confidence
Finding

This markdown file presents the rubric entirely in Chinese, which can amount to a language/locale policy violation when the skill forces a specific language without user opt-in. There is no note indicating that the rubric is intentionally region-specific or that alternative language support is available.
