Harvest Time Reporting

• Outcome: Review
• Latest audit: Sep 10, 2026 · 8:10 AM UTC
• Version: 1.0.0

Overview

The skill is a Harvest API reference, but it exposes broad business, financial, and account-changing actions without clear guardrails.

Install only if you intend agents to access and potentially modify Harvest data. Use a least-privileged Harvest token, avoid broad admin tokens where possible, and require explicit user confirmation before creating, updating, deleting, sending invoices, or changing company/account records.

A.I.G

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally
• Unauthorized Access and Privilege Escalation: Obtains permissions beyond the task's legitimate needs

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 91% confidence

Finding

The skill documents broad access to third-party endpoints handling time tracking, users, invoices, contacts, company, and reporting data, but provides no privacy, retention, consent, or data-sharing notice. In an agent setting, omission of these warnings can lead operators to transmit sensitive business and personal data to an external SaaS without adequate awareness or governance.
