Security audit

Google Drive

Security checks for vulnerabilities and agentic risk

Overview

This Google Drive skill is mostly coherent, but its first-time setup recommends running remote install scripts directly in a shell, which deserves review before use.

Review the oo CLI installation path before installing. Prefer a verified package or documented manual installation method, and only allow this skill to modify or delete Drive content 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

Finding

The skill instructs the agent/user to install software via a remote script piped directly into a shell (curl ... | bash), which executes unverified code from the network with the user's privileges. If the hosting endpoint, CDN, TLS trust chain, or install script is compromised, this becomes an immediate arbitrary code execution path.

Finding

The description says to use this skill for "ANY Google Drive request" and "Whenever a task involves Google Drive," which is an expansive activation condition that can overlap with many ordinary tasks involving Drive. It does not provide scope limits, exclusions, or negative examples to clarify when the skill should not be invoked.
