Email Management

Security checks for vulnerabilities and agentic risk

Overview

This email-management skill is a local, user-directed workflow aid with disclosed storage and approval gates for sensitive actions.

Before installing, decide whether you want this skill active only on explicit request or only for a specific account/project. Its local memory may contain email preferences, contacts, deadlines, and follow-up commitments, so keep the ~/email-management/ folder protected and avoid storing raw email dumps, passwords, tokens, or payment details.

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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The activation guidance recommends triggering on broad everyday terms like 'email', 'inbox', 'reply', or 'follow-up', which are likely to appear in many unrelated conversations. This can cause unintended skill invocation, leading to inappropriate access to email-related context, unnecessary persistence of user data, or confusing autonomous behavior outside the user's intended scope.
