Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed paid image-enhancement workflow, but users should be aware it can install a CLI, use an API token, and upload images to an external service.

Install only if you are comfortable using Qinghu's paid image workflow, uploading the chosen image to that service, and configuring a qhkit token. Confirm costs before generation, avoid using sensitive or unauthorized images, and prefer explicit approval before installing or upgrading Node/qhkit.

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
94% confidence
Finding

The activation description includes broad natural-language triggers such as requests to make an image 'more realistic' or '高清', which are common in ordinary conversation. Overbroad invocation criteria can cause the skill to trigger unexpectedly and steer the agent into installing software, requesting credentials, or initiating paid workflows without sufficiently explicit user intent.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The '何时触发' examples are ambiguous and lack limiting conditions, so ordinary image-editing requests could invoke this skill unintentionally. In this skill's context, accidental activation is more dangerous because the skill then guides installation, token setup, pricing checks, and external workflow execution.

Confidence
84% confidence
Finding

The skill instructs use of npx @iqinghu/qhkit without pinning an exact version, which makes execution depend on whatever package version is current at runtime. This creates a supply-chain and reproducibility risk: a compromised or breaking upstream release could be fetched and executed automatically in the user's environment.

Session Persistence

Medium
Category
Rogue Agent
Confidence
60% confidence
Finding

Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
