Security audit

Audio Tool

Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple FFmpeg-based audio helper with no bundled code, persistence, credential use, or hidden behavior found.

Install this if you are comfortable using an FFmpeg-backed audio utility and understand the Chinese documentation. As with any media-processing skill, review the files you ask it to process and the FFmpeg commands your agent plans to run.

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

Natural-Language Policy Violations

Medium
Confidence
94% confidence
Finding
The skill metadata and primary user-facing documentation are written entirely in Chinese, with no indication that users may interact in another language or choose a locale. The policy requires flagging language or locale constraints when they are imposed without user opt-in or clear justification.
