Google Sheets Fdds Report

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward Google Sheets reporting helper with disclosed, purpose-aligned read and optional write behavior.

Before installing, be aware that the skill may read business/logistics data from a Google Sheet and can write the generated report back if you ask it to. Use least-privilege Google access and specify the spreadsheet, tab, and range for any write operation.

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

Missing User Warnings

Confidence

Finding

The skill explicitly permits writing generated report content back into the Google Sheet, but it does not require explicit user confirmation, scope limitation, or safeguards against overwriting existing spreadsheet data. In a tool connected to live business documents, this can cause unintended modification or corruption of operational data or templates if the agent writes to the wrong range or acts on an ambiguous request.

Natural-Language Policy Violations

Finding

Natural-language policy issues apply to all file types, including markdown. Here the skill appears to force Spanish-only instructions and outputs without documenting a language choice, which can violate language/locale policy when no opt-in or justification is provided.
