SuperBooks: Chasing Unpaid Invoices
Security checks for vulnerabilities and agentic risk
Overview
This skill only guides the agent to read unpaid invoice information from SuperBooks and draft reminders for the user to send manually.
Before installing, confirm you are comfortable letting the agent read unpaid invoice, customer contact, and revenue-context data from SuperBooks for receivables review. The skill tells the agent not to send emails or change invoices; users should still review any drafted reminder before sending it themselves.
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
