Expense

Security checks for vulnerabilities and agentic risk

Overview

This is a plain expense-tracking guidance skill with no executable code, external access, or hidden installation behavior.

Installers should treat this as a finance-assistance skill and avoid pasting unnecessary sensitive financial details. Consider narrowing activation triggers or requiring confirmation when a broad term like budget or receipt appears outside an expense-tracking request.

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 trigger list contains generic everyday finance terms such as 'expense', 'budget', 'receipt', and 'subscription' that are likely to appear in many unrelated conversations. This can cause unintended activation of the skill, leading the agent to enter a financial-records workflow when the user did not explicitly request it, which may expose or collect sensitive financial context unnecessarily.
