# CVE-2026-15785: Joinchat <= 6.3.1 - Reflected Cross-Site Scripting via '{HREF}' Dynamic Variable

Status: published. Published: 2026-11-11. Updated: 2026-11-11.

The Joinchat – Enhanced "click to chat" plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via '{HREF}' Dynamic Variable via Query Parameter Name in all versions up to, and including, 6.3.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. Exploitation requires that an administrator has configured a telephone number and included the {HREF} dynamic variable in the Call-to-Action text.
