UAPI Epic 免费游戏 接口

Security checks for vulnerabilities and agentic risk

Overview

This skill is a small, disclosed wrapper for checking Epic Games free-game information through UAPI, with no executable code or hidden local access.

Before installing, be aware that the skill calls uapis.cn for Epic free-game data and may ask you to use a UAPI key if free anonymous quota is exhausted. For generic game-information requests, confirm the agent is not using this narrow Epic free-games skill by mistake.

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

Vague Triggers

Finding

The keyword "游戏资料" is much broader than the skill’s actual capability, which is limited to the Epic free-games endpoint. This can cause the agent to route unrelated game-information requests to this skill, leading to incorrect API use, misleading responses, or unnecessary exposure of external-call behavior. In this context the issue is operational rather than directly exploit-enabling, but overly broad triggers increase the chance of misrouting and unsafe tool selection.

Natural-Language Policy Violations

Medium

Confidence
92% confidence
Finding

This markdown file contains user-facing instructions and descriptions only in Chinese, which can amount to a language policy violation when no user opt-in or alternative locale is offered. The policy specifically calls for flagging skills that force a specific language without user choice unless the locale constraint is clearly documented and justified.

Finding

The file’s operational guidance is presented primarily in Chinese, which can impose a language expectation on users or agents without documenting a language choice. The policy specifically calls for flagging language or locale constraints when they are forced without opt-in or clear justification.
