DeepRead Invoice Processing

• Outcome: Pass
• Latest audit: Sep 16, 2026 · 4:35 AM UTC
• Version: 1.0.0

Overview

This skill is a straightforward DeepRead invoice-processing guide that clearly sends user-chosen invoice documents to DeepRead's external API and does not install code or modify the system.

Install only if you are comfortable sending selected invoices, receipts, or bills to DeepRead's hosted service using your API key. Check your organization's rules for confidential financial documents, retention, and regulated data before uploading real customer, vendor, tax, or payment information.

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

Vulnerability Patterns

• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Supply Chain: Unpinned Dependencies, External Script Fetching, Obfuscated Code
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access
• Excessive Agency: Unrestricted Tool Access, Autonomous Decision Making, Scope Creep

Findings (5)

External Script Fetching

High

• Category: Supply Chain
• Confidence: 90% confidence

Finding

Remote code is downloaded and executed. This bypasses code review and could introduce malicious code.

External Script Fetching

High

• Category: Supply Chain
• Confidence: 90% confidence

Finding

Remote code is downloaded and executed. This bypasses code review and could introduce malicious code.

  echo "  Status: $STATUS"

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 93% confidence

Finding

The skill explicitly instructs users to upload invoices, receipts, purchase orders, and bills to a third-party API, but it does not provide a prominent privacy, confidentiality, retention, or compliance warning. These documents commonly contain sensitive financial, business, and personal data, so omission of a clear warning can lead users to transmit regulated or confidential information without informed consent.

Content

No source excerpt is available for this finding.

External Transmission

Medium

• Category: Data Exfiltration
• Confidence: 95% confidence

Finding

This cURL example sends the full invoice file and extraction schema to an external domain, which is an intentional data exfiltration path to a third-party service. Because invoices often contain financial, tax, vendor, and personal information, the external transmission creates privacy, confidentiality, and compliance risk if users are not expecting the transfer or if the service's handling is unclear.

External Transmission

Medium

• Category: Data Exfiltration
• Confidence: 50% confidence

Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
