Email & Newsletter

Security checks for vulnerabilities and agentic risk

Overview

This skill provides newsletter strategy and drafting guidance while explicitly keeping email sending, metrics, consent, and platform setup under human/external control.

Before installing, expect this skill to help plan and draft newsletters and related social posts. It should not send email, buy lists, fabricate reporting, or operate an ESP for you; keep actual sending and metric access in human-controlled external tools.

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

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
