Security checks for vulnerabilities and agentic risk

Overview

This skill does what it says by publishing Xiaohongshu long-form posts, but it can perform a real public account action from a somewhat broad trigger without a clear user-controlled final confirmation.

Review this skill carefully before installing. It is not malicious, but users should only invoke it when they intend to publish to a real Xiaohongshu account, and they should require a final manual confirmation before the publish button is clicked.

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
Vulnerability Patterns
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Finding

The trigger phrases include broad language such as “写一篇小红书”, which can match ordinary content-writing requests rather than an intent to actually publish. In this skill’s context, activation causes navigation to a live publishing flow on the user’s Xiaohongshu account, so ambiguous triggering can lead to unintended external actions.

Missing User Warnings

Confidence

Finding

The skill does not clearly warn that it will perform a real posting action on the user’s external Xiaohongshu account. Because the workflow culminates in clicking a live “发布” button, a user may believe they are only drafting or formatting content when the skill is actually making an irreversible public-facing account action.
