WordPress Video Carousel Slider with Lightbox Reflected Cross-Site Scripting Vulnerability

A reflected cross-site scripting vulnerability has been identified in the Video Carousel Slider with Lightbox plugin for WordPress, affecting versions through 1.0.22. The issue arises from inadequate input sanitization and output escaping, allowing unauthenticated attackers to inject arbitrary web scripts via the search_term parameter. These scripts could be executed if a user is tricked into clicking a link.

Impact

Exploitation of this vulnerability allows for reflected cross-site scripting, where an attacker can inject malicious scripts that are executed in the context of the user's browser.

Reproduction

To reproduce this vulnerability, send a request to a page that uses the affected WordPress plugin. Include the search_term parameter with the injected script. If the payload is executed, the vulnerability is confirmed.

Remediation

Users are advised to update the plugin to version 1.0.23 or later, where this vulnerability has been patched.
