Security audit

Guaikei Kuaishou Creator Finder

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed Kuaishou public-data collection tool that calls a third-party API and saves local result logs, with no evidence of hidden execution or malicious behavior.

Install only if you are comfortable sending Kuaishou keywords, profile or video URLs, and your GUAIKEI_API_TOKEN to guaikei.com. Be aware that retrieved public data is saved locally under the skill's logs directory, so clear those files if the searches or results are sensitive on a shared machine.

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

Missing User Warnings

Medium
Confidence
89% confidence
Finding
The script persists full search results to a local file automatically, but does not provide a clear runtime warning or require opt-in before storing potentially sensitive query history and result data. On shared systems or CI environments, this can leak user interests, collected content, or metadata to other local users/processes through residual files.
