How to fix?

Upgrade Debian:unstable firefox to version 48.0-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream firefox package and not the firefox package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

Mozilla Firefox before 48.0 does not properly restrict drag-and-drop (aka dataTransfer) actions for file: URIs, which allows user-assisted remote attackers to access local files via a crafted web site.
