Hex

Security checks for vulnerabilities and agentic risk

Overview

This Hex connector skill is coherent, but it needs review because its fallback setup tells agents to install the OOMOL CLI by executing a remote script directly.

Install only if you trust OOMOL and are comfortable connecting it to Hex. Avoid letting an agent run the remote installer automatically; prefer reviewing the official install instructions, using a pinned release, and verifying integrity before installation. Confirm every run_project or cancel_run action before execution.

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 skill instructs the agent/user to install software by piping a remotely fetched script directly into a shell (curl ... | bash). This bypasses integrity verification, exposes execution to supply-chain compromise or server-side tampering, and is especially risky in a skill file because it operationalizes code execution as part of normal task recovery flow.
