Solar Wizard Lite Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the Solar Wizard Lite plugin for WordPress, affecting all versions through 1.2.4. The issue arises from inadequate input sanitization and output escaping of user-supplied attributes in the plugin's 'solar_wizard' shortcode. This vulnerability allows authenticated attackers with contributor-level access or higher to inject arbitrary scripts into pages, which are executed when users access the affected pages.

Impact

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

Reproduction

To reproduce this vulnerability, an authenticated user with contributor-level access or higher can use the 'solar_wizard' shortcode without proper sanitization. This can be done by injecting a script into one of the shortcode's attributes, which will then be executed when the page is viewed.

Remediation

Users are advised to update the Solar Wizard Lite plugin to version 1.2.5 or later.
