Image Magic resizer

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward ImageMagick image resizer with ordinary file output risks but no hidden or high-impact behavior found.

Before installing, understand that this tool can create output directories and write image files wherever you point it. Use a distinct output path if you do not want to risk replacing an existing file.

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

Finding

This markdown file describes a command that performs image resizing on user-provided files, but it does not disclose any risk around overwriting an existing output path or otherwise altering user data. For a file-manipulating skill, a brief warning about output-file handling would improve user awareness and reduce accidental data loss.
