Security checks for vulnerabilities and agentic risk

Overview

The skill mostly matches its stated Xiaohongshu research purpose, but it automatically saves full fetched results and URL tokens in a predictable temporary folder without clear user control.

Review before installing if you work on shared machines or handle sensitive research targets. Running the skill sends your keywords or Xiaohongshu URLs to guaikei.com with your API token, and successful results are automatically saved locally in a temp log folder. Avoid URLs containing sensitive access parameters where possible, delete local logs after use, and prefer an updated version that makes saving opt-in, redacts xsec_token, and writes with private permissions.

Vulnerability Patterns

Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
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

High

Category: MCP Tool Poisoning
Confidence: 99% confidence
Finding: The description foregrounds topic planning, but the skill also performs external API searches and writes results to disk without an explicit capability boundary. In an agent ecosystem, this matters because users may invoke what seems like a planning helper without realizing it can transmit queries to a third party and retain outputs locally.
Content: No source excerpt is available for this finding.
