Moojing Market Intelligence

Security checks for vulnerabilities and agentic risk

Overview

The skill is coherent for managing Moojing data, but it includes an unsafe remote installer fallback that should be reviewed before use.

Before installing, review the oo CLI installer source or use a safer trusted installation method where available; only approve write or destructive Moojing actions after checking the exact target and payload.

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/user to install software by piping a remotely fetched script directly into a shell (curl ... | bash). This creates a supply-chain and remote-code-execution risk because any compromise of the hosting domain, transport, or script contents would immediately execute arbitrary code on the target system. In this skill context, the danger is elevated because the install step is embedded as an operational fallback inside a trusted automation workflow, making unsafe execution more likely.
