CVE-2020-7011

Elastic App Search versions before 7.7.0 contain a cross site scripting (XSS) flaw when displaying document URLs in the Reference UI.

MEDIUM 6.1EPSS 1.01%

Does this matter?

Lower severity and a low EPSS score (1.01%). Track it; it rarely justifies an emergency change on its own.

Description

Elastic App Search versions before 7.7.0 contain a cross site scripting (XSS) flaw when displaying document URLs in the Reference UI. If the Reference UI injects a URL into a result, that URL will be rendered by the web browser. If an attacker is able to control the contents of such a field, they could execute arbitrary JavaScript in the victimï¿½s web browser.
