Title
Cross-Site Scripting (XSS) stored in Tawk Live Chat
Summary
Cross-site Scripting (XSS) stored vulnerability in Tawk Live Chat. This vulnerability allows an attacker to execute JavaScript code in the victim's browser by uploading a malicious PDF with JavaScript payload through the chatbot. The PDF is stored by the application and subsequently displayed without proper sanitisation when other users access it. This vulnerability can be exploited to steal sensitive user data, such as session cookies, or to perform actions on behalf of the user.
