Security audit

fal.ai

Security checks for vulnerabilities and agentic risk

Overview

The skill is focused on fal.ai through OOMOL, but its setup can execute an unverified remote installer if the CLI is missing.

Review the first-time setup before installing. Prefer verifying the oo CLI installer through OOMOL's documented install guide or a signed/package-manager installation path, and do not let the agent run the installer automatically unless you trust that source. Once installed, the skill's fal.ai actions are reasonably scoped and write/destructive actions should require your explicit approval.

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

High
Category
Supply Chain
Confidence
98% confidence
Finding

The skill instructs users to install software by piping a remote script directly into a shell (curl ... | bash), which executes unverified code from the network with the user's privileges. If the install endpoint, transport, hosting, or upstream distribution is compromised, this can lead to arbitrary code execution and full workstation or environment compromise.

Confidence

Finding

The description says to use this skill for "ANY fal.ai request," which is an extremely broad invocation condition and lacks boundaries or exclusion cases. This can cause unintended activation for routine mentions of fal.ai because the trigger scope is not narrowly defined.
