# Define restricted downloadable MIME types

# Define restricted downloadable MIME types {#ariaid-title1}

Release version: Australia  
Updated March 12, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Use the glide.ui.attachment.force_download_all_mime_types property to download MIME types and not to render inline in the browser.
If the glide.ui.attachment.download_mime_types property doesn't include dangerous MIME types such as text/html, image/svg, image/svg+xml, application/xml, and application/xhtml+xml, dangerous files could be rendered
inline in the browser. This can lead to cross-site scripting attacks (XSS).

This property is the list of comma-separated attachment mime types that don't render inline in the browser. For example, including text/html forces
HTML files to be downloaded to the client as attachments rather than viewed inline in the browser. Maintaining this list properly prevents XSS attacks.  
Note:  
This check is only relevant when glide.ui.attachment.force_download_all_mime_types is set to false.

If glide.ui.attachment.force_download_all_mime_types is set to false, verify that the glide.ui.attachment.download_mime_types system property includes the
dangerous MIME types <kbd class="ph userinput">text/html, image/svg, image/svg+xml, application/xml, and application/xhtml+xml</kbd>.
