yamcs-web is vulnerable to Cross-site Scripting (XSS). The vulnerability is present because there is insufficient validation when uploading files in the library. This flaw enables an attacker to upload an HTML file that contains arbitrary JavaScript. When a user opens this file, the arbitrary JavaScript is executed, potentially leading to malicious actions or unauthorized access through the bucket.
