## Description

A stored Cross-Site Scripting (XSS) vulnerability in the notification
template functionality of the endpoint /ocsreports/?function=notification.
A user with administrator privileges can input malicious HTML content which
is subsequently stored and displayed without proper sanitisation when other
administrators access the template customisation view, allowing JavaScript
code to be executed within the application’s security context and
potentially compromising the sessions of other users with administrative
privileges.
