Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed Qinghu creator-data workflow that installs and uses qhkit to collect specified public creator profile metrics and export an Excel file, with payment estimation before submission.

Install only if you are comfortable using Qinghu's qhkit CLI, providing a Qinghu API token, and submitting creator profile URLs to Qinghu for a paid or subscription-gated workflow. Confirm the estimate before generation and prefer a reviewed/pinned qhkit install where your environment requires tighter supply-chain control.

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
Category
Not specified by scanner
Confidence
95% confidence
Finding

The metadata says this skill 'must trigger' for broad classes of common analytics requests, which can cause the agent to invoke external tooling and data collection when the user may only want discussion or lightweight analysis. In this skill's context, invocation can lead to package installation, credential setup, scraping-style collection of third-party account data, and paid workflow submission, so overbroad triggering materially increases risk.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The example phrases are ordinary business-language requests that overlap with harmless conversation, yet they are presented as invocation triggers. Because this skill performs networked workflow execution and may install software or request API keys, ambiguous trigger phrases increase the chance of unintended tool execution, unnecessary data collection, or surprise charges.

Finding

The skill recommends running npx @iqinghu/qhkit without pinning an exact package version. That causes execution of whatever version is current at invocation time, creating a supply-chain risk where behavior can change unexpectedly or a compromised package release could execute arbitrary code in the user's environment.

Session Persistence

Medium
Category
Rogue Agent
Confidence
60% confidence
Finding

Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
