Security audit

Knowledge Paid

Security checks for vulnerabilities and agentic risk

Overview

This is a simple Chinese-language guidance skill for choosing paid education content and it does not include code, hidden execution, credential use, persistence, or data exfiltration behavior.

Install only if you want Chinese-language help comparing and subscribing to paid education content. Use legitimate trials, subscriptions, and provider-approved downloads; the artifact itself does not grant or request account access.

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

Medium

Confidence
91% confidence
Finding

The example trigger phrases are extremely broad and resemble ordinary user requests, which can cause the platform to invoke this skill for generic learning or 'how to use' questions rather than explicit requests for this specific capability. In this context, that is more dangerous because the skill is framed around obtaining access to paid content guides, so accidental triggering could route normal educational queries into potentially policy-violating or unauthorized acquisition guidance.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
84% confidence
Finding

The skill metadata and all user-facing instructions are entirely in Chinese, with no indication that the user can choose another language or that the locale restriction is intentional and justified. This can be a language/locale policy issue when a skill implicitly enforces one language without opt-in.
