Manus Agent

Security checks for vulnerabilities and agentic risk

Overview

This is a simple Chinese-language guidance skill about using Manus Agent, with no executable code or hidden privileged behavior.

Installers should understand that this skill is mainly Chinese-language guidance for using Manus-style autonomous tasks. Review its examples and keep normal user confirmation around logins, payments, and sensitive web actions, but the artifact itself does not add code or privileged access.

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 manifest description and main instruction text are written as a Chinese-only assistant persona (e.g., '助手') and do not indicate that the user may choose another language. Under the policy for natural-language violations, forcing a specific language without opt-in is a reportable locale/language constraint.
