Security audit

Email Sequence Designer

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed email lifecycle planning aid with limited, purpose-aligned memory use and no bundled executable code.

Before installing, expect this skill to help plan email automation flows and optionally reference marketing-platform exports or connector workflows. Review any generated broadcast request before approving live sends, and keep consent and suppression checks in place.

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 display name, summary, and description include mandatory Chinese text in addition to English, but the file does not explain that the skill is region-specific or offer a language choice. This creates a natural-language locale policy issue because the skill imposes a specific language presentation without documented user opt-in.
