Security audit

FraudLabs Pro

Security checks for vulnerabilities and agentic risk

Overview

This integration needs review because it treats order submissions as reads and directs automatic execution of an unverified installer when its CLI is missing.

Before use, require approval of screening payloads, customer-data sharing through OOMOL, and credit consumption. Install a reviewed, fixed CLI release separately and check its automatic skill synchronization settings. The external installer and connector implementation were not verified; the bundled skill shows no evidence of intentional malicious behavior.

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

Findings (6)

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied command runs a remote installer rather than accessing FraudLabs Pro data. Nothing in the chunk establishes that this installation supports the declared integration. The downloaded script's contents are not supplied, so its further effects cannot be determined.

No source excerpt is available for this finding.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
88% confidence
Finding

The supplied code only initiates a CLI login. It contains no FraudLabs Pro reference or data operations, and nothing establishes that this authentication is a supporting step for FraudLabs Pro. The visible behavior therefore does not substantiate the declared purpose. The service targeted by oo cannot be determined from this chunk.

External Script Fetching

High
Category
Supply Chain
Confidence
97% confidence
Finding

Piping a mutable HTTPS response directly into bash executes remote code without verifying its contents or release identity. Compromise of the installer delivery path could yield arbitrary code execution with the agent's local privileges; HTTPS and a legitimate dependency relationship do not eliminate that supply-chain risk.

The untagged `screen_order` action is incorrectly classified as a read safe to run without confirmation.

Medium
Category
Excessive Agency
Confidence
96% confidence
Finding

The blanket rule that untagged actions are reads incorrectly includes screen_order, which submits an order for processing rather than merely retrieving an existing result. Screening can create a transaction, transmit sensitive order information, and consume service quota or credit, so this classification bypasses the skill's own confirmation safeguard.

Content

No source excerpt is available for this finding.

The setup workflow executes downloaded installation scripts without warning the user about running remote code or modifying their system.

Medium
Category
Output Handling
Confidence
94% confidence
Finding

A missing CLI triggers instructions to install software by immediately executing a downloaded script, without an explicit approval checkpoint or integrity verification. This can modify the host and execute arbitrary code with the invoking user's privileges; the missing-command condition limits exposure but does not authorize those changes.

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.
