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 description says the skill should be called whenever access or automation related to Xiaohongshu is needed, which is a broad trigger that can cause the agent to invoke this skill in many loosely related situations. Overbroad activation increases the chance of unnecessary browsing or data-collection actions on a third-party site, including in contexts where the user did not clearly request this specific platform workflow.
