Email Render Builder

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent email HTML build and render-QA helper with no hidden execution or unrelated data access found.

Before installing, confirm you are comfortable with a skill that can help draft email HTML and, on confirmation, save render-QA handoffs to memory. Treat any live ESP test send as an explicit action and use only your own verified sender and test inboxes.

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 name, summary, and description include Chinese-language text alongside English, but the file does not state that bilingual output is optional or limited to a China-specific context. That can conflict with a language/locale policy requiring user choice or explicit justification for locale constraints.
