MEDIUM 5.3EPSS 1.27%

Does this matter?

Lower severity and a low EPSS score (1.27%). Track it; it rarely justifies an emergency change on its own.

Description

Style editor traffic in the Developer Tools can be routed through a service worker hosted on a third party website if a user selects error links when these tools are open. This can allow style editor information used within Developer Tools to leak cross-origin. This vulnerability affects Firefox < 58.
