Exploit

Snipe-IT: Stored XSS via inline-served attachment

Snipe-IT is an IT asset/license management system. 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. This issue is fixed in version 8.6.2.
