Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed integration for generating ecommerce videos through qhkit, with ordinary but nonzero setup and credential risks.

Before installing, confirm you are comfortable with npm-based tool installation, qhkit storing or using your API token, and possible user-level Node/qhkit environment changes. Review credit estimates carefully because video generation consumes account credits after confirmation.

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
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

92% confidence
Finding

The skill instructs use of npx @iqinghu/qhkit without pinning a specific version. That makes execution depend on whatever package version is current at runtime, increasing supply-chain risk and enabling unexpected or malicious package updates to be pulled and executed. In this skill context, the command is intended to install and run tooling, so the risk is real rather than theoretical.

Session Persistence

Medium
Category
Rogue Agent
Confidence
89% confidence
Finding

This duplicate finding points to the same behavior: unpacking Node.js into a user directory and exporting a modified PATH, with instructions to persist the change across shells. That creates session persistence and environment drift, which can affect future unrelated operations and weakens the principle of least surprise in shared or semi-trusted execution contexts.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

Line L077 instructs the agent to avoid using international-site responses and says the CLI message is already user-facing Chinese, while other guidance repeatedly mandates relaying Chinese prompts and messages to the user. This establishes a Chinese-language interaction constraint without offering the user a language choice or opt-in, which is a natural-language locale policy concern.

Confidence
90% confidence
Finding

The skill recommends npx --yes sharp-cli without a version pin, which causes arbitrary current registry content to be fetched and executed when image compression is needed. Because this path is an automatic fallback inside the workflow, it increases the chance that an agent executes unreviewed third-party code from the package registry. The skill context makes this more dangerous because it is framed as an automated remediation step, not a consciously reviewed install.
