Skill QR Card

Security checks for vulnerabilities and agentic risk

Overview

This skill has a clear QR-card purpose, but its generator exposes a real local command-execution risk through the custom output path.

Review this skill before installing. It should be safe only when used with trusted, simple output filenames or with PNG conversion disabled, but it should be fixed to avoid shell execution and to constrain output paths before broad use.

Vulnerability Patterns

Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
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
