Listen Notes

Security checks for vulnerabilities and agentic risk

Overview

The skill mostly performs read-only Listen Notes actions, but its setup instructions can run an unverified remote installer on the user's machine.

Install only if you are comfortable with OOMOL's oo CLI and its Listen Notes connector. Avoid letting an agent run the curl|bash or irm|iex installer automatically; install the CLI manually from trusted official instructions and verify what will run first.

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 remote script directly into a shell (curl ... | bash). This creates a supply-chain and remote code execution risk: if the remote host, transport, or script content is compromised, arbitrary code will run immediately on the user's machine without verification.

Finding

Line L03 says to use the skill for "ANY Listen Notes request" and "Whenever a task involves Listen Notes," which is a very broad activation condition without exclusions or narrower scope constraints. This can cause unintended invocation for loosely related mentions of Listen Notes rather than clearly defined user intents.
