Security audit

OpenGame Browser Game Builder

Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed browser-game prototyping skill with no hidden executable code, persistence, or credential handling.

Install this skill if you want help making focused browser-game prototypes. Be aware that it may activate for general game-improvement requests, so users should phrase non-browser or non-prototype game questions clearly if they do not want code-generation help.

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

Finding

The activation text is broad enough to match many ordinary game-related requests, which can cause the skill to trigger in situations where a narrower or more specialized skill would be more appropriate. Over-broad routing is dangerous because it can unexpectedly steer user requests into a code-generation workflow, increasing the chance of unintended file modifications, scope creep, or misuse of project context.
