Security checks for vulnerabilities and agentic risk

Overview

This is a simple email-reply writing skill with no code execution or hidden behavior, but users should avoid pasting unnecessary sensitive email details.

Use this skill for drafting replies, but share only the minimum email context needed. Redact credentials, private identifiers, confidential business details, signatures, and irrelevant personal information before pasting content.

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

Finding

The skill explicitly encourages users to paste full email content, which commonly contains personal data, confidential business information, credentials, links, signatures, or other sensitive context. Without any warning, minimization guidance, or redaction instructions, users may overshare sensitive information into the system, creating avoidable privacy and data-handling risk.
