MEDIUM 6.5EPSS 2.45%

Does this matter?

Lower severity and a low EPSS score (2.45%). Track it; it rarely justifies an emergency change on its own.

Description

The Resource Timing API incorrectly revealed navigations in cross-origin iframes. This is a same-origin policy violation and could allow for data theft of URLs loaded by users. This vulnerability affects Firefox < 57, Firefox ESR < 52.5, and Thunderbird < 52.5.
