CVE-2025-48483 Information

Description

FreeScout is a free self-hosted help desk and shared mailbox. Prior to version 1.8.180 the application is vulnerable to Cross-Site Scripting (XSS) attacks due to incorrect input validation and sanitization of user-input data during mail signature sanitization. An attacker can inject arbitrary HTML code including JavaScript scripts into the page processed by the user’s browser allowing them to steal sensitive data hijack user sessions or conduct other malicious activities. Additionally if an administrator accesses one of these emails with a modified signature it could result in a subsequent Cross-Site Request Forgery (CSRF) vulnerability. This issue has been patched in version 1.8.180.
