Security audit

Browser Smart Click

Security checks for vulnerabilities and agentic risk

Overview

The skill does what it says, but its default browser automation can automatically accept cookie or consent prompts for the user.

Install only if you are comfortable with the skill automatically dismissing overlays during browser automation. For privacy-sensitive browsing or sites with legal terms, use auto_dismiss=False or review consent dialogs manually before allowing clicks.

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

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

This markdown file contains substantial user-facing instructional content in Chinese, including usage guidance and examples, while the manifest does not indicate that the skill is region-specific or Chinese-only. Under the language/locale policy, forcing a specific language without opt-in or justification is a natural-language policy violation.

Missing User Warnings

Confidence

Finding

The documentation explicitly promotes automatic dismissal of cookie banners and dialogs, including matching consent-related text such as 'accept', 'agree', and 'allow', without warning that this may submit legal/privacy choices on the user's behalf. In a browser automation skill, this is risky because it can silently grant tracking consent or dismiss important notices, causing unintended user actions and compliance/privacy issues.

Missing User Warnings

Confidence

Finding

The skill automatically clicks consent/accept buttons on detected cookie or consent banners without user confirmation, which can silently alter privacy choices and create unauthorized state changes on third-party sites. In an automation context, this may accept tracking, legal terms, or other prompts beyond the user's intent because matching is based on broad text heuristics such as 'accept', 'agree', 'allow', and 'ok'.

Natural-Language Policy Violations

Finding

Natural-language strings in the module docstrings, comments, and CLI output are written in Chinese, which imposes a specific language choice on users without opt-in or justification. The file does not state that it is intended only for a Chinese-speaking or region-specific audience.

Intent-Code Divergence

Confidence

Finding

The inline comment at L125 says the code searches for buttons containing × or Close text, and L131 says it returns null 'but marks text match found'. In actual behavior, this function has no separate marker or side channel; it simply returns null, so callers cannot distinguish 'found by text' from 'not found at all'. This is a documentation-to-code contradiction, albeit low impact.
