Security checks for vulnerabilities and agentic risk

Overview

The skill matches its audio-extraction purpose, but it asks users to provide and store a service API key and sends video links through a third-party tool without enough privacy guidance.

Review this before installing if you are not comfortable giving the agent a qhkit API key or sending platform share links to qhkit. Prefer configuring the token locally yourself, avoid pasting secrets into chat, and revoke the key if it is exposed or no longer needed.

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

Vague Triggers

Medium
Category

Confidence
91% confidence
Finding

The skill metadata says requests to extract audio/BGM 'must trigger', using broad mandatory activation language tied to common user intents. This can cause over-invocation on ambiguous requests, leading the agent to perform external-link processing or tool use without sufficient confirmation, which increases privacy and safety risk.

Missing User Warnings

Confidence
95% confidence
Finding

The skill instructs the operator to have the user create and send an API key and to process third-party share links, but it provides no warning about secret handling, data exposure, or trust boundaries. Asking users to transmit tokens in chat is dangerous because credentials may be logged, retained, or misused, and submitted links may expose private or copyrighted content to external services.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
88% confidence
Finding

The instructions state '本技能对接国内版' and explicitly say not to guide users to the international site, forcing a specific locale/service variant. This is a language/locale policy concern because the skill does not offer the user a choice or document a justified region-specific constraint.
