Cn Json Diff

Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple local JSON comparison tool, with only a minor unrelated promotional footer in Chinese.

This appears safe to use for local JSON comparisons. Users should be aware that the documentation includes third-party promotional links; opening those links is separate from using the local diff script.

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 file is primarily written in English, but the closing promotional section switches to Chinese-only text and links without any opt-in or language selection. This creates a natural-language locale inconsistency that may violate language-choice expectations for users who do not read Chinese.
