Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward Google Workspace CLI helper, but users should understand that OAuth access can expose or modify Gmail, Calendar, Drive, Sheets, Docs, and Contacts data.

Install only if you want an agent-assisted CLI to access your Google Workspace data. Use the narrowest OAuth services and scopes that fit your task, verify the Homebrew formula before installing, and explicitly review commands that send email, create calendar events, update sheets, or clear sheet ranges.

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

Credential Access

High
Category
Privilege Escalation
Confidence
70% confidence
Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
