Description
FreeScout is a free help desk and shared inbox built with PHP's Laravel framework. Prior to version 1.8.211, host header manipulation in FreeScout version (http://localhost:8080/system/status) allows an attacker to inject an arbitrary domain into generated absolute URLs. This leads to External Resource Loading and Open Redirect behavior. When the application constructs links and assets using the unvalidated Host header, user requests can be redirected to attacker-controlled domains and external resources may be loaded from malicious servers. This issue has been patched in version 1.8.211.
