**Elastic App Search Cross Site Scripting flaw (ESA-2020-04)**

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 victim’s web browser.

**Affected Versions**  
All versions before 7.7.0 are vulnerable to this issue.

**Solutions and Mitigations**  
Users should upgrade to Elastic Enterprise Search version 7.7.0. There is no known workaround for this issue.

**CVSSv3: 5.9 - AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:N**  
**CVE ID: [CVE-2020-7011](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-7011)**
