Visitor Traffic Real Time Statistics WordPress Plugin Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the Visitor Traffic Real Time Statistics plugin for WordPress, affecting all versions through 8.4. The issue arises from inadequate input sanitization and output escaping, allowing unauthenticated attackers to inject arbitrary scripts. These scripts are executed when an admin user accesses the 'Traffic by Title' section.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user viewing the affected page.

Reproduction

To reproduce this vulnerability, an unauthenticated user can inject a script through the 'page_title' parameter. Once injected, the script will execute when an admin user accesses the 'Traffic by Title' section.

Remediation

Users are advised to update the plugin to version 8.5 or later.
