Security audit

lux3d

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent Lux3D API client that sends user-provided prompts and asset URLs to Lux3D and downloads results when requested.

Install only if you intend to use Lux3D/Aholo's hosted service. Do not submit confidential models, images, prompts, or private URLs unless you are comfortable sending them to that service, and keep LUX3D_API_KEY out of logs and shared transcripts.

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

Direct Prompt Extraction

High
Category
System Prompt Leakage
Confidence
85% confidence
Finding

Skill contains instructions that could directly expose system prompts, internal rules, or hidden instructions to users or external parties.

python
"""Validate a text-to-3D prompt."""
    if not isinstance(prompt, str) or not prompt.strip():
        raise ValueError("prompt must be non-empty text")
    return prompt.strip()

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
94% confidence
Finding

The skill invokes network access and depends on environment-stored credentials, but the manifest does not declare tool scope or permissions boundaries. That omission weakens reviewability and least-privilege controls, making it easier for an operator or hosting platform to grant broader execution capability than users expect.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The skill instructs users to provide publicly accessible asset URLs to a third-party API without an upfront privacy warning. This can expose private models or images to unintended public access or third-party retention if users upload sensitive assets and make them externally reachable.

External Transmission

Medium
Category
Data Exfiltration
Confidence
60% confidence
Finding

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

Unbounded Resource Access

Medium
Category
Excessive Agency
Confidence
75% confidence
Finding

Skill allows unbounded resource consumption (API calls, storage, compute). Without rate limits or quotas, a compromised or misbehaving agent can cause denial-of-service or cost overruns.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
88% confidence
Finding

The skill tells users to export and pass an API key in an authorization header but does not warn about secure secret handling. In practice this increases the chance of credential leakage through shell history, logs, screenshots, copied commands, or accidental disclosure when debugging.
