Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed Chinese-language integration for submitting short-video links to Qinghu's qhkit workflow and exporting paid analytics results.

Before installing, understand that this skill uses Qinghu's qhkit CLI, may install Node/qhkit, sends the video links you provide to Qinghu's service, and requires a Qinghu token for paid workflow execution. Prefer a reviewed or pinned qhkit version if your environment requires strict supply-chain control, and only provide links and credentials you are comfortable using with the Qinghu service.

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
  • Rogue AgentSelf-Modification, Session Persistence
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
88% confidence
Finding

The activation section uses phrases like '帮我统计这些视频的数据' and '导出视频数据表', which are fairly broad natural-language requests and may overlap with ordinary analytics or spreadsheet-help requests. Although the file names supported platforms elsewhere, this trigger list does not provide negative examples or clear limits on when this skill should not activate.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
84% confidence
Finding

The instructions mandate Chinese field names and Chinese option values, and state that CLI messages should be relayed in Chinese, but do not offer an opt-in or alternative language path. This can violate language/locale policy when a skill is user-invocable and does not explicitly state that it is limited to Chinese-language operation for a justified regional-only reason.

Finding

The skill recommends running npx @iqinghu/qhkit <命令> ... without pinning an exact package version. That allows execution of whatever version is current at install time, which can change behavior unexpectedly or introduce a compromised release into the user's environment.

Session Persistence

Category
Rogue Agent
Confidence
78% confidence
Finding

This duplicate finding describes the same behavior: installing a runtime into a user-controlled directory and prepending it to PATH. That persistence can alter future command resolution and weakens provenance and change control compared with managed installations.
