Security audit

Preference Frequency Manager

Security checks for vulnerabilities and agentic risk

Overview

This skill is a plain Markdown planning aid for email preference-center design, with disclosed memory handoffs and no hidden code or execution behavior.

Before installing, be aware that the skill is meant to work with email preference, opt-out, and consent-related data. Use sanitized exports where possible, confirm before saving memory notes, and review any proposed suppression or cadence rules before applying them in an ESP or consent registry.

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 Chinese text by default, but the file does not state that the skill is region-specific or that multilingual output is optional. This can violate language/locale policy where skills should not impose a specific language without user choice or documented justification.
