Invoice Tracker Pro

Security checks for vulnerabilities and agentic risk

Overview

This is a plain Markdown invoice-workflow skill whose financial-data use is expected for its purpose, with no hidden code or persistence found.

Before installing, treat this as a billing assistant for drafting and organizing financial workflows. Do not paste raw bank credentials, tax IDs, or processor secrets into prompts; verify client identities, invoice amounts, payment links, and consent before sending reminders or initiating any payment-related action through external tools.

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 centers on invoices, payment links, auto-charging, reconciliation, and syncing with accounting platforms, all of which inherently involve sensitive financial, business, and personal data. Without explicit guidance on secure handling, minimization, storage, sharing, and verification of payment/account details, users may expose bank information, tax IDs, client PII, or send reminders/charges based on inaccurate or over-broad data flows.
