Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed e-commerce image generation helper that uses a qhkit CLI and external service, with installation and token setup risks users should review.

Before installing, confirm you trust @iqinghu/qhkit and the iqinghu service, because the skill may install npm tooling, use an API token, and upload product images for generation. Prefer a reviewed or pinned qhkit version if reproducibility matters, and avoid adding PATH changes to shell startup files unless you intentionally want the tools available in future 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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill declares that it 'must trigger' for broad, common e-commerce requests such as generating product detail pages, without clear exclusion criteria or user-confirmation boundaries. Overly broad activation can cause the agent to invoke external tooling unexpectedly, increasing the chance of unnecessary data exposure, unreviewed command execution, or misuse in contexts where the user did not explicitly consent.

Confidence
90% confidence
Finding

The skill instructs use of npx @iqinghu/qhkit without pinning a specific version, which permits execution of whatever package version is current at invocation time. That increases supply-chain risk and undermines reproducibility, especially because the skill also encourages bootstrap installation and command execution in the local environment.

Session Persistence

Medium
Category
Rogue Agent
Confidence
88% confidence
Finding

The same installation block creates a user-scoped runtime location and alters PATH, enabling persistent availability of newly installed binaries in later sessions. Even though the text includes checksum verification, the persistence behavior remains risky because it normalizes permanent environment changes as part of routine skill execution.
