MEDIUM 5.3EPSS 2.39%

Does this matter?

Lower severity and a low EPSS score (2.39%). Track it; it rarely justifies an emergency change on its own.

Description

If right-to-left text is used in the addressbar with left-to-right alignment, it is possible in some circumstances to scroll this text to spoof the displayed URL. This issue could result in the wrong URL being displayed as a location, which can mislead users to believe they are on a different site than the one loaded. This vulnerability affects Thunderbird < 52.6, Firefox ESR < 52.6, and Firefox < 58.
