Array Url Extractor

Security checks for vulnerabilities and agentic risk

Overview

This skill only gives instructions for extracting URLs from user-provided arrays and does not request system access, persistence, or sensitive data handling.

Before installing, note that the skill is intended to output only extracted URLs with no explanation. Users should provide only arrays or snippets they are comfortable processing, but the artifact itself does not contain code or request sensitive authority.

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

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
