Security audit

Browser Download

Security checks for vulnerabilities and agentic risk

Overview

This skill teaches browser-based file downloads in a straightforward way, with no hidden execution, persistence, or data access beyond saving requested downloads.

Install this only if you want ADA to help download files through the browser. Review the source site and filename before using it, and do not open or execute downloaded files unless you trust their origin.

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

The skill description and content are broad enough to enable invocation for downloads from essentially any webpage, without constraining trusted domains, file types, or user-confirmation requirements. In an agent setting, this can lead to unintended use on untrusted pages and facilitate retrieval of malicious or sensitive files through overly general automation guidance.
