Name of the Vulnerable Software and Affected Versions Firefox versions prior to 57

Description The issue is related to the implementation of the Referrer Policy in Mozilla Firefox. When a document's Referrer Policy attribute is set to "no-referrer", sometimes two network requests are made for "" elements instead of one, with one of these requests including the referrer despite the policy. This could allow a remote attacker to gain unauthorized access to protected information.

Recommendations For versions prior to 57, update to version 57 or later to resolve the issue.
