Security audit

Invoice Chaser Pro

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward invoice reminder email generator, with minor caution that its trigger words and file tool declarations are broader than the task strictly needs.

Installers should expect this skill to help draft payment reminder emails using invoice details they provide. Consider narrowing activation triggers or invoking it explicitly in sensitive finance workflows, and only allow file read/write access when working with specific user-selected invoice or template files.

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 is broad enough to match common business phrases such as 'invoice,' 'overdue,' and 'follow up on invoice,' which can cause the skill to activate in ordinary accounting or email-drafting contexts where the user did not explicitly request this workflow. Unintended activation can steer conversations into collections-oriented content and expose billing details or generate inappropriate reminders in the wrong context.
