Security audit

Lightcone Browse

Security checks for vulnerabilities and agentic risk

Overview

This is a coherent cloud browser automation skill, but it needs review because broad autonomous web actions can send user data or submit forms without explicit guardrails.

Install only if you are comfortable delegating browsing to Lightcone's cloud browser. Avoid secrets unless necessary, and require explicit user confirmation before logins, payments, form submissions, posting, account changes, or handling confidential business or personal data.

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
Vulnerability Patterns

  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Medium

Confidence
95% confidence
Finding

The activation text is very broad and matches common requests like browsing websites, scraping pages, checking prices, filling forms, or operating web apps. That creates a real risk of unintended invocation of a powerful browser-automation skill, which can cause external actions, data submission, and retrieval of screenshots/page content without sufficiently deliberate user intent.

Missing User Warnings

Medium
Category

Confidence
96% confidence
Finding

The skill describes cloud-based browser automation that can type into forms and return page content and screenshots, but it does not warn users that their prompts and entered data may be sent to external websites and processed in a remote environment. In this context, the omission is dangerous because users may unknowingly disclose sensitive personal, account, or business information to third parties or have sensitive on-screen data captured in screenshots.
