Security audit

Statista

Security checks for vulnerabilities and agentic risk

Overview

The Statista functions fit the stated purpose, but setup directs the agent to run an unverified remote installer without a separate approval step.

Review and approve CLI installation separately, prefer a pinned and verified release, and review or disable automatic skill synchronization. OOMOL mediates your Statista access. The concern is installation control and broader agent changes; the inspected artifact does not establish malicious intent.

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
98% confidence
Finding

The supplied code performs remote script execution, not Statista searching or reading. Nothing provided establishes that this installer is a necessary supporting implementation detail for the declared functionality. The downloaded script's contents are unavailable, so its further behavior cannot be assessed.

No source excerpt is available for this finding.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The curl-to-bash command executes mutable remote content without a pinned version or independent integrity verification. Compromise of the installation endpoint or delivery pipeline could execute attacker-controlled code with the agent's privileges, potentially exposing accessible files and credentials; the PowerShell alternative has the same underlying risk.

The fallback setup executes downloaded installation scripts without warning about remote code execution or system changes.

Medium
Category
Output Handling
Confidence
94% confidence
Finding

The fallback directs the agent to execute remote installers when the CLI is missing, without requiring user approval for running third-party code or modifying the local environment. The error-gated setup reduces exposure, but a request to read Statista data does not itself authorize software installation with the agent's local privileges.

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.
