Vulnerability Title
CtrlPanel: Stored XSS in Ticket Reply Notifications Allows Session Hijacking
Source: NVD (National Vulnerability Database)
Vulnerability Description
CtrlPanel is open-source billing software for hosting providers. Versions 1.1.1 and prior contain a Stored Cross-Site Scripting (XSS) vulnerability in the ticket reply notification system. Unsanitized reply content ($newmessage) is stored directly in database notification payloads and later rendered unescaped via Blade's {!! !!} syntax in the recipient's browser. The flaw exists in both App\Notifications\Ticket\Admin\AdminReplyNotification (triggered when a user replies, targeting admins) and App\Notifications\Ticket\User\ReplyNotification (triggered when an admin replies, targeting users), allowing arbitrary JavaScript execution in the victim's session context. A low-privileged attacker can exploit this to hijack admin sessions, harvest credentials via fake login prompts or keyloggers, and escalate privileges by performing administrative actions on the victim's behalf. The reverse path also enables a malicious or compromised admin to target regular users in the same manner. This issue has been fixed in version 1.2.0.

Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
CtrlPanel.gg是CtrlPanel.gg开源的一款主机服务计费管理工具。 CtrlPanel.gg 1.1.1及之前版本存在跨站脚本漏洞，该漏洞源于工单回复通知系统中未对回复内容进行清理，直接存储到数据库通知负载中，并通过Blade的{!! !!}语法未转义渲染，可能导致存储型跨站脚本攻击。
