Email Bot

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed email-sending integration that posts user-provided email details to AIProx/Resend using a spend token.

Before installing, understand that email contents, recipient addresses, and the spend token are sent to AIProx to trigger delivery through Resend. Use explicit fields for important emails, verify recipients before sending, and only send messages you are authorized to send.

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
