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

Description The issue exists due to insufficient input validation in the browser, allowing a remote attacker to spoof the location bar by using special characters in the media type of a data: URL. This can be achieved through crafted characters in the data:URL type.

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 data:URL types until a patch is applied. Avoid using special characters in the media type of a data:URL to minimize the risk of exploitation.
