Browser Automation

Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed browser automation skill with no bundled executable code, but users should be careful with login sessions, scraping, uploads, and anti-bot handling.

Install only if you are comfortable with an agent performing browser actions you explicitly request. Be especially cautious when reusing login sessions or cookies, uploading files, submitting forms, scraping sites, using proxies, or handling anti-bot flows; keep those actions scoped to accounts and sites where you have permission.

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

Natural-Language Policy Violations

Medium
Confidence
98% confidence
Finding
The skill description and all operational instructions are written in Chinese, with no indication that users may interact in another language or that the skill is intended only for a Chinese-speaking or region-specific context. This creates a natural-language policy concern because it implicitly enforces a specific language without user opt-in.
