Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple WeChat article fetch helper that uses a disclosed public third-party API and does not show persistence, credential access, or destructive behavior.

Install only if you are comfortable sending WeChat article URLs to the public down.mptext.top service. Avoid using it for private, access-controlled, or sensitive links unless you trust that service's handling of request data.

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

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill instructs the agent to send user-supplied WeChat article URLs to a public third-party service (down.mptext.top) but does not clearly warn users that their requested links and associated access metadata will be disclosed externally. This creates a privacy and data-handling risk, especially if users assume the fetch happens locally or directly against WeChat.
