## Technical details

A Stored Cross-Site Scripting (XSS) vulnerability exists in CtrlPanel <= 1.1.1 due to improper sanitization of ticket reply content ($newmessage). The application stores raw reply data in database notification payloads and subsequently renders it unescaped using Blade's {!! !!} syntax. The flaw affects both AdminReplyNotification and UserReplyNotification classes. A low-privileged attacker can inject malicious JavaScript into a ticket reply; when an administrator views their notification feed, the script executes in their session context. This enables session hijacking, credential harvesting, and administrative privilege escalation. The issue is fixed in version 1.2.0 by implementing strip_tags() on notification content.
