Qr Generator

Security checks for vulnerabilities and agentic risk

Overview

This skill does what it says: it generates QR codes from user-provided text or URLs, with ordinary local file output and no hidden execution behavior found.

Install only if you are comfortable with npm dependencies and local file generation. Avoid encoding secrets unless that is intentional, use a temporary output path, delete generated QR files when done, and treat Feishu sharing or terminal output as potentially logged or visible to others.

A.I.G

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

Missing User Warnings

Low
Confidence
88% confidence
Finding
The skill invites users to encode arbitrary text or URLs into a QR code image or terminal output, but it does not warn that the supplied content may itself be sensitive and will be persisted to disk or exposed in terminal/session logs. This can lead to inadvertent disclosure of secrets such as WiFi credentials, tokens, internal URLs, or personal data when images are shared, stored, or transmitted via Feishu.
