Security audit

Message Tracker Plugin

Security checks for vulnerabilities and agentic risk

Overview

This is a lightweight Feishu message-push skill whose webhook and secret handling are disclosed and aligned with its stated purpose.

Before installing, confirm you are comfortable with Chinese-only instructions and only configure Feishu webhooks for channels where these tracked messages should appear. Treat the webhook URL and optional secret as credentials and avoid committing them to public repositories.

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
