Morning (Green Invoice)

Security checks for vulnerabilities and agentic risk

Overview

This is a straightforward Morning/GreenInvoice helper that handles sensitive accounting actions, but its behavior is disclosed, scoped, and proportionate to that purpose.

Only install this if you want an agent to create or modify Morning/GreenInvoice business records using your API credentials. Provide language, currency, client, and document details explicitly for important accounting documents, and treat API secrets and JWTs as sensitive.

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

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 96% confidence
