MEDIUM 5.3EPSS 1.30%
Does this matter?
Lower severity and a low EPSS score (1.30%). Track it; it rarely justifies an emergency change on its own.

Image for moz-icons can be accessed through the "moz-icon:" protocol through script in web content even when otherwise prohibited. This could allow for information leakage of which applications are associated with specific MIME types by a malicious page. This vulnerability affects Firefox < 59.
