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.
