PinchTab Browser Ops

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed PinchTab browser-automation guide with a Xiaohongshu draft workflow, and I did not find hidden execution, exfiltration, or destructive behavior.

Install only if you want an agent to operate websites through PinchTab using your active browser session. Review actions before allowing publishing or form submission on sensitive sites, and reserve eval fallback for explicit, temporary troubleshooting.

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 entire skill is written to operate specifically in Chinese, including Chinese UI labels, trigger text, and content-writing requirements such as '真人经验口吻'. There is no indication that the user can choose another language or that the locale restriction is optional, which matches the policy concern for forced language/locale behavior.
