Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent e-commerce video-generation helper, but users should notice that it installs command-line tooling, stores an API token, uploads media, and can spend paid credits after confirmation.

Install only if you are comfortable giving qhkit an API key, uploading the selected product images or videos to the service, and approving paid credit usage. Prefer pinned dependency versions and avoid adding PATH changes to shell startup files unless you want the toolchain to persist across sessions.

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
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • 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
Findings (6)

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The description states the skill '完美融合中文语境' and is written as a mandatory routing/usage description without offering any language or locale choice. This can violate language/locale policy because it implicitly constrains usage to Chinese-language output rather than presenting it as an opt-in or region-specific option.

Confidence
95% confidence
Finding

The skill instructs use of npx @iqinghu/qhkit without pinning an exact package version. That allows execution of whatever version is current in the registry at runtime, creating a supply-chain risk if the package is updated maliciously, compromised, or changed incompatibly.

Session Persistence

Medium
Category
Rogue Agent
Confidence
82% confidence
Finding

This finding is a duplicate report of the same session-persistence behavior: unpacking Node into the user's home directory and exporting a modified PATH, with text suggesting possible persistence across shells. In an agent skill, instructions that establish long-lived toolchain changes increase the risk of unintended persistence and future misuse of the modified environment.

Finding

The skill uses npx --yes sharp-cli without a fixed version, so it may download and execute arbitrary newly published code from the registry during runtime. Because this command is suggested as an automatic fallback for image processing, it expands the attack surface beyond the primary toolchain.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
87% confidence
Finding

The example for qhkit video-quick generate includes "language":"zh", which specifies a fixed language in natural-language-facing behavior. Because the surrounding guidance does not clearly frame this as an example only or require user consent for language selection, it may conflict with language/locale choice expectations.
