Name of the Vulnerable Software and Affected Versions Mozilla Firefox versions prior to 48.0

Description The issue is related to improper restriction of drag-and-drop operations for file: URL objects, which can be exploited by a remote attacker using a specially crafted website to access local files. This can allow user-assisted remote attackers to obtain access to local files.

Recommendations For versions prior to 48.0, update to version 48.0 or later to resolve the issue. As a temporary workaround, consider restricting the use of drag-and-drop functionality in Firefox until a patch is applied.
