Finlight

Security checks for vulnerabilities and agentic risk

Overview

The skill mostly performs read-only Finlight searches through OOMOL, but its setup instructions include running an unverified remote installer script directly in a shell.

Install only if you are comfortable using OOMOL as an intermediary for Finlight access. Before running the setup commands, prefer official installation documentation and verify the installer source; do not let an agent run the remote shell installer automatically.

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 bypasses integrity verification and turns a network or supply-chain compromise of the install endpoint into immediate arbitrary code execution on the host running the skill. In this context, the skill is specifically telling an agent/operator what to execute, which makes the unsafe pattern more dangerous because it is presented as an endorsed recovery step.
