Security audit

Financial Tracker

Security checks for vulnerabilities and agentic risk

Overview

This is a simple financial-tracking skill that formats and summarizes user-provided business transactions, with one minor promotional link in the README but no evidence of hidden execution or data exfiltration.

Before installing, treat any financial details you provide as sensitive and avoid entering data you do not want the assistant to process. The external context-pack link in the README appears promotional and is not required for the skill's basic financial-tracking use.

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 skill documentation is focused on local business income/expense tracking, CSV export, and financial summaries, but L31 advertises external 'context-packs' via a URL and pricing. Promoting unrelated products is not justified by the stated purpose of a financial tracker and introduces an external-facing capability that is outside the described scope.
