What an attacker can do

The source says prior to 8.6.2, UploadFileRequest sanitizes SVG content only when PHP finfo reports image/svg+xml and UploadedFilesController serves attachments inline without using StorageHelper::allowSafeInline(), allowing a low-privilege user to upload active XHTML or XML content that is later served same-origin and executes JavaScript in a viewer’s browser. Vendor/CNA’s CVSS 4.0 assessment (base score 6.2/10) rates confidentiality, integrity and availability impact as none.
