Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed paid qhkit workflow for generating TVC advertising videos from user-provided product images, with expected external uploads and credit usage.

Install only if you are comfortable trusting the qhkit npm package and the iqinghu service with your product images, API token configuration, and paid credit usage. Confirm the estimate before generation, avoid uploading unlicensed or sensitive assets, and prefer pinned or reviewed package versions in controlled environments.

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
92% confidence
Finding

The description says this skill 'must trigger' for a broad set of common advertising requests, which can cause overbroad activation and unnecessary delegation. In an agent setting, broad mandatory triggers can override user intent, increase the chance of unintended tool use, and funnel many generic requests into a third-party workflow that may consume credits or expose user assets.

Finding

The skill recommends falling back to npx @iqinghu/qhkit without pinning an exact version. That causes execution of whatever package version is current at runtime, expanding supply-chain risk and reducing reproducibility if a compromised or breaking release is published.

Session Persistence

Medium
Category
Rogue Agent
Confidence
83% confidence
Finding

This duplicate finding points to the same persistence behavior: unpacking Node into a user-controlled directory and exporting it into PATH. In a tool-executing agent context, such setup can outlive the current task and broaden the blast radius of any upstream compromise or later misuse of the installed runtime.
