Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed e-commerce video-generation skill, but users should understand it installs and runs an external CLI, uses an API token, and uploads provided media to the service.

Install only if you trust the qhkit/iqinghu service and are comfortable sending selected product images or videos to it. Prefer reviewed or pinned qhkit versions where possible, avoid adding PATH changes to shell startup files unless needed, and treat API tokens and paid-credit generation as deliberate user-approved steps.

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

High
Category
Not specified by scanner
Confidence
95% confidence
Finding

The manifest says generic requests to generate or make videos 'must trigger' this skill, using very broad matching terms. That can cause over-invocation and unsafe routing, where unrelated user requests are pushed into an external tool flow that may install software, request credentials, or send media to third-party services without sufficiently specific user intent.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
89% confidence
Finding

The description is written to force Chinese-language behavior and Chinese-platform assumptions regardless of the user's preferred language. This is mainly a policy/UX issue, but it can become a security concern if it leads users to follow instructions they do not understand, especially around installation, authentication, and third-party service usage.

MCP Rug Pull
Confidence
95% confidence
Finding

The skill instructs use of npx @iqinghu/qhkit without pinning a specific version, which makes execution depend on whatever package version is current at runtime. That creates a supply-chain risk: a compromised latest release or unexpected breaking update could execute unreviewed code on the host during fallback installation.

Session Persistence

Medium
Category
Rogue Agent
Confidence
89% confidence
Finding

The skill directs installation of Node into $HOME/.local/lib and modifies PATH, with later guidance to persist it in shell startup files. Even though framed as setup, this establishes user-level persistence and changes future command resolution, increasing the blast radius if the installed binaries or fetched archives are ever compromised.
