expense-compliance

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed expense-audit API integration with clear limits and no evidence of hidden execution, persistence, payment actions, or data exfiltration.

Before installing, confirm you are comfortable sending receipt images, OCR text, policy data, and claim details to the AI Skills platform. Prefer the product-specific EXPENSE_COMPLIANCE_API_KEY if you want tighter credential scope, and avoid putting full API keys or full tax/receipt identifiers into chat logs or exported reports.

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
Vulnerability Patterns
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
