CVE-2017-7842
This vulnerability affects Firefox < 57.
MEDIUM 5.3EPSS 1.54%
Does this matter?
Lower severity and a low EPSS score (1.54%). Track it; it rarely justifies an emergency change on its own.
Description
If a document's Referrer Policy attribute is set to "no-referrer" sometimes two network requests are made for "<link>" elements instead of one. One of these requests includes the referrer instead of respecting the set policy to not include a referrer on requests. This vulnerability affects Firefox < 57.
