Snipe-IT is an IT asset/license management system. Prior to 8.6.2, the user edit flow stores url()->previous() from the attacker-controlled Referer header into Laravel’s intended URL session value and later uses redirect()->intended(...) when redirect_option=back is submitted, allowing Snipe-IT to be used as a trusted redirector after a legitimate user edit action. This issue is fixed in version 8.6.2.
