MEDIUM 5.3EPSS 1.87%

Does this matter?

Lower severity and a low EPSS score (1.87%). Track it; it rarely justifies an emergency change on its own.

Description

If a site is loaded over a HTTPS connection but loads a favicon resource over HTTP, the mixed content warning is not displayed to users. This vulnerability affects Firefox < 63.
