### Impact The user edit flow stores `url()->previous()` into Laravel's intended URL session value and later redirects with `redirect()->intended(...)` when `redirect_option=back` is submitted. Because the previous URL is derived from the attacker-controlled `Referer` header, an authenticated user performing a normal user-edit action can be redirected to an external attacker-controlled site.

An attacker who can cause a logged-in user with permission to edit a user record to open the edit page with an attacker-controlled `Referer` value.

The application can be used as a trusted redirector after a legitimate user edit action. This can support phishing or trust-boundary attacks against Snipe-IT users and matches a historical open redirect class where session-stored navigation context influences redirect destinations.
