Riddle Quiz Maker

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly coherent for managing Riddle Quiz Maker through OOMOL, but its setup instructions tell the agent to run remotely downloaded installer scripts without integrity verification.

Install only if you trust OOMOL and are comfortable with the oo CLI managing your Riddle Quiz Maker connection. Prefer installing the CLI out of band from official documentation, review the installer first, and require explicit confirmation before any publish, rename, tag removal, or unpublish action.

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

External Script Fetching

Finding

The skill instructs the agent to install software by piping a remotely fetched script directly into a shell (curl ... | bash). This is a real supply-chain risk because any compromise of the hosting domain, TLS termination, DNS, or the install script itself would lead to immediate arbitrary code execution on the user's machine without inspection or integrity verification.
