Gog Jarvis

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward guide for using a Google Workspace CLI, with sensitive Google account access disclosed and aligned to its purpose.

Install only if you trust the gog CLI and are comfortable granting it access to the selected Google services. Use the least-privileged Google account and service set practical, and require explicit confirmation before sending email, creating calendar events, or changing/clearing Sheets data.

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
Content: Use `gog` for Gmail/Calendar/Drive/Contacts/Sheets/Docs. Requires OAuth setup. Setup (once) - `gog auth credentials /path/to/client_secret.json` - `gog auth add you@gmail.com --services gmail,calendar,drive,contacts,sheets,docs` - `gog auth list`
Confidence: 70% confidence
Finding: Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
