WP Bulk SMS by SMS.to Reflected Cross-Site Scripting Vulnerability

A reflected cross-site scripting vulnerability has been identified in the WP Bulk SMS by SMS.to plugin for WordPress, affecting all versions through 1.0.12. The issue arises from inadequate input sanitization and output escaping, allowing unauthenticated attackers to inject arbitrary web scripts via the 'page' parameter. These injected 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 scripts that are executed in the context of the user's browser.
