Description
The Floating Chat Widget: Contact Chat Icons, Telegram Chat, Line Messenger, WeChat, Email, SMS, Call Button, WhatsApp – Chaty plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘data-hover’ parameter in all versions up to, and including, 3.3.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
