CVE-2020-15665

This vulnerability affects Firefox < 80.

MEDIUM 4.3EPSS 0.69%

Does this matter?

Lower severity and a low EPSS score (0.69%). Track it; it rarely justifies an emergency change on its own.

Description

Firefox did not reset the address bar after the beforeunload dialog was shown if the user chose to remain on the page. This could have resulted in an incorrect URL being shown when used in conjunction with other unexpected browser behaviors. This vulnerability affects Firefox < 80.
