CVE-2008-5026: Microsoft SharePoint Server

Low severity, CVSS 3.5. EPSS: 9.4% chance of exploitation in the next 30 days.

Microsoft SharePoint uses URLs with the same hostname and port number for a web site's primary files and individual users' uploaded files (aka attachments), which allows remote authenticated users to leverage same-origin relationships and conduct cross-site scripting (XSS) attacks by uploading HTML documents.
