Security audit

Vercel

Security checks for vulnerabilities and agentic risk

Overview

The Vercel integration is mostly coherent, but it tells agents to run an unverifiable remote installer and can perform broad Vercel account changes.

Review before installing. Use the skill only if you trust OOMOL and its oo CLI distribution path, prefer installing the CLI manually from a verified source, and require explicit confirmation for any Vercel write or destructive action.

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 via curl ... | bash, which executes a remote script directly without prior verification. If the distribution endpoint, network path, or hosting account is compromised, this can lead to arbitrary code execution on the user's machine; in an agent context, the risk is amplified because the skill normalizes this behavior as a fallback path during operation.

Finding

The description says to use this skill for "ANY Vercel request" and for any task that "involves Vercel," which is an extremely broad trigger scope. It does not provide boundaries, exclusions, or negative examples to clarify when the skill should not be invoked.
