What is CVE-2025-48483?

FreeScout, a self-hosted help desk application, is vulnerable to Cross-Site Scripting (XSS) attacks due to inadequate input validation during mail signature processing. This flaw allows attackers to inject arbitrary HTML or JavaScript into user-facing pages, potentially compromising user data, hijacking sessions, or executing other harmful actions. Moreover, if an admin interacts with an email containing a tampered signature, it could trigger a Cross-Site Request Forgery (CSRF) vulnerability. This issue was addressed in version 1.8.180.
