Security audit

Ue Build Package

Security checks for vulnerabilities and agentic risk

Overview

This skill is a project-specific Unreal Engine build helper with no hidden code, network access, credential use, or persistence.

Before installing, confirm the hardcoded SilverPalace paths and target names match your project. Treat the cache deletion and IDE automation notes as manual troubleshooting steps, not automatic actions.

A.I.G

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

Natural-Language Policy Violations

Low

Confidence: 92% confidence
Finding: The build target descriptions are presented in Chinese (e.g. 'Windows 客户端', '编辑器', '服务器版本') while the rest of the document is primarily in English. This imposes a language preference without user opt-in and no region-specific justification is provided in the file.

Static analysis

No suspicious patterns detected.
