Security audit

Kuwo

Security checks for vulnerabilities and agentic risk

Overview

This skill is a small Kuwo Music helper for light analysis of public pages, with no bundled code, persistence, or hidden execution behavior.

Before installing, expect this skill to guide an agent in browsing and summarizing Kuwo Music pages. Keep use limited to public pages or explicitly requested personal-page organization, and avoid downloads, bulk scraping, account actions, or attempts to bypass platform controls.

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

Finding

The description says the skill should be invoked whenever access or automation related to Kuwo content is needed, which is broader than the narrowly scoped behavior described later in the file. Overly broad activation can cause the agent to route unrelated or higher-risk requests into this skill, increasing the chance of unintended browsing or data collection actions on a third-party site.

Finding

All user-facing natural-language content in the skill file is presented only in Chinese, with no indication that users may choose another language or locale. Under the stated policy, a skill should not implicitly force a specific language unless the locale restriction is clearly documented and justified or the user is given a choice.
