## Overview

* **Rule ID**: `javascript_react_google_analytics`

## Description

Sending sensitive data to Google Analytics can lead to data leaks. This vulnerability occurs when confidential or sensitive information is unintentionally sent to Google Analytics, creating a risk of unauthorized access and potential data breaches.

## Remediation Guidelines
