Official 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.

Technical Analysis

CVE-2026-34241 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), with a CVSS base score of 8.7.

The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.

From a weakness classification perspective (CWE-79): Cross-site scripting (XSS) vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users.
