Wangdian ERP

• Outcome: Review
• Latest audit: Nov 3, 2026 · 11:09 AM UTC
• Version: 1.0.4

Overview

The ERP operations fit the stated purpose, but setup can execute unverified downloaded software without a clear user checkpoint.

Review and verify the CLI installation before allowing automatic setup, and use a connection limited to the ERP data you need. The installer and live service behavior could not be inspected. Also review the CLI's broader skill synchronization; its [command reference](https://raw.githubusercontent.com/oomol-lab/oo-cli/main/docs/commands.md) documents OO_SKILLS_SYNC_DISABLED for disabling startup synchronization.

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

• Supply Chain: Unpinned Dependencies, External Script Fetching, Obfuscated Code
• Excessive Agency: Unrestricted Tool Access, Autonomous Decision Making, Scope Creep
• MCP Tool Poisoning: Hidden Instructions, Unicode Deception, Parameter Description Injection
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration

Findings (3)

Description-Behavior Mismatch

High

• Category: MCP Tool Poisoning
• Confidence: 97% confidence

Finding

The supplied chunk performs remote installer execution and contains no Wangdian ERP queries or data-reading operations. Nothing in the provided content establishes that this installer is a supporting dependency for the declared ERP functionality. The downloaded script's contents and any further effects cannot be determined from this chunk.

Content

No source excerpt is available for this finding.

External Script Fetching

High

• Category: Supply Chain
• Confidence: 98% confidence

Finding

The installation command executes a remotely fetched, mutable script immediately without verifying its integrity or reviewing its contents; the PowerShell alternative has the same weakness. A compromised distribution endpoint could execute arbitrary code with the agent's local privileges, potentially exposing files and credentials. Restricting installation to a missing-CLI error reduces exposure, but does not make that execution safe.

Autonomous Decision Making

Medium

• Category: Excessive Agency
• Confidence: 80% confidence

Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
