MEDIUM 6.5EPSS 1.20%

Does this matter?

Lower severity and a low EPSS score (1.20%). Track it; it rarely justifies an emergency change on its own.

Description

Marked 2 through 2.5.11 allows remote attackers to read arbitrary files via a crafted HTML document that triggers a redirect to an x-marked://preview?text= URL. The value of the text parameter can include arbitrary JavaScript code, e.g., making XMLHttpRequest calls.
