## Technical details

A stored cross-site scripting (XSS) vulnerability exists in the IRIS web application (specifically version 2.4.26) within the datastore upload function. The application fails to properly neutralize user-supplied input during the file upload process, allowing an attacker to inject malicious scripts. This vulnerability is triggered when a victim views the uploaded content. An attacker requires low-level authenticated access to exploit this flaw. Successful exploitation can lead to session hijacking, sensitive data exposure, or unauthorized administrative actions due to the 'Scope: Changed' (S:C) nature of the vulnerability.
