Manus

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly a coherent Manus connector, but its setup instructions tell the agent to execute a remotely downloaded installer directly in the shell.

Review this before installing. The Manus actions are clearly described and state-changing operations require confirmation, but the setup instructions should be treated carefully: do not let an agent run the remote installer automatically. Prefer a verified package-manager install or manually download, inspect, and verify the oo CLI installer from OOMOL before executing it.

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 skill instructs the agent to install software by piping a remotely fetched script directly into a shell (curl ... | bash). This is dangerous because it executes unverified code from the network with the user's privileges, and if the endpoint, transport, hosting, or supply chain is compromised, arbitrary code execution can occur immediately. In this skill context, the risk is elevated because the content is an operational runbook for an agent, making automated or semi-automated execution of the unsafe install path more likely.
