MEDIUM 6.5EPSS 1.75%
Does this matter?
Lower severity and a low EPSS score (1.75%). Track it; it rarely justifies an emergency change on its own.
Description
A combination of an external SVG image referenced on a page and the coloring of anchor links stored within this image can be used to determine which pages a user has in their history. This can allow a malicious website to query user history. Note: This issue only affects Firefox 57. Earlier releases are not affected. This vulnerability affects Firefox < 57.0.1.
