TelSender < 1.14.15 - Unauthenticated Stored XSS via Telegram Chat Title

Description

The plugin is vulnerable to DOM-Based Cross-Site Scripting due to insufficient input sanitization when processing Telegram API responses containing attacker-controlled chat titles. This makes it possible for unauthenticated attackers to inject malicious scripts via Telegram chat titles that execute when an administrator opens the TelSender settings page and clicks the "Tested" button.
