CVE-2018-5119

This could allow access to content that should be restricted in reader view.

MEDIUM 5.3EPSS 1.56%

Does this matter?

Lower severity and a low EPSS score (1.56%). Track it; it rarely justifies an emergency change on its own.

Description

The reader view will display cross-origin content when CORS headers are set to prohibit the loading of cross-origin content by a site. This could allow access to content that should be restricted in reader view. This vulnerability affects Firefox < 58.
