Security audit

Kuaimai ERP

Security checks for vulnerabilities and agentic risk

Overview

The ERP workflow is coherent, but setup directs the agent to execute unverified downloaded code without a separate approval step.

Before use, install and verify a fixed CLI release yourself and require approval for setup changes. Review or disable its automatic agent-skill synchronization. Connect only the ERP account you intend OOMOL to access, and retain confirmation for writes. The bundled instructions were fully inspected; downloaded installers and hosted connector behavior remain unverified.

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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
94% confidence
Finding

The visible behavior is remote software installation rather than ERP data access or modification. Although installing a CLI could be a supporting implementation detail, the supplied code provides no evidence connecting this installer to Kuaimai ERP. The downloaded script's contents are not supplied, so its subsequent actions cannot be determined.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The command streams a mutable remote script directly into Bash without verifying its integrity or authenticity beyond HTTPS. Compromise of the distribution endpoint could therefore execute attacker-controlled code with the invoking user's privileges, potentially exposing local files and credentials; this is a legitimate dependency setup path, not evidence of malicious intent.

Fallback setup executes downloaded installer scripts without warning about remote-code execution or local system changes.

Medium
Category
Output Handling
Confidence
94% confidence
Finding

The fallback directs the agent to execute downloaded shell or PowerShell code without an explicit installation approval step or an explanation of local system changes. Restricting setup to a missing-CLI error reduces exposure, but an ERP request does not itself authorize arbitrary local software installation; actual execution also depends on enforced tool permissions.

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.
