Gog Litiao

Security checks for vulnerabilities and agentic risk

Overview

This is a straightforward Google Workspace CLI helper, with expected but sensitive access to Google mail, calendar, drive, contacts, docs, and spreadsheets.

Install only if you trust the gog Homebrew source and are comfortable granting it the Google Workspace scopes you enable. Review commands that send mail, create calendar items, or change Sheets data before running them, especially sheets clear.

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

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.

Missing User Warnings

Medium
Confidence
90% confidence
Finding
The markdown lists `gog sheets update`, `append`, and `clear`, which can modify or erase spreadsheet data. While line L36 warns about sending mail or creating events, there is no comparable warning for spreadsheet writes or clears that could affect user data integrity.
