Plain English Summary

AI-powered analysis for quick understanding

This vulnerability allows an attacker, even with a low-level user role like a subscriber, to execute SQL injection attacks, which means they could manipulate the database to access or alter sensitive information. The issue arises from the plugin not properly cleaning up user input in a specific function, making it accessible to any authenticated user.

Technical Description

The WP Visitor Statistics (Real Time Traffic) WordPress plugin before 4.8 does not properly sanitise and escape the refUrl in the refDetails AJAX action, available to any authenticated user, which could allow users with a role as low as subscriber to perform SQL injection attacks
