**Elasticsearch information disclosure (ESA-2021-03)**

Elasticsearch versions before 7.10.0 and 6.8.14 have an information disclosure issue when audit logging and the emit\_request\_body option is enabled. The Elasticsearch audit log could contain sensitive information such as password hashes or authentication tokens. This could allow an Elasticsearch administrator to view these details.

**Affected Versions:**

All versions of Elasticsearch before 7.10.0 and 6.8.14 are affected by this flaw

**Solutions and Mitigations:**

Anyone using audit logging with the xpack.security.audit.logfile.events.emit\_request\_body enabled should upgrade to Elasticsearch version 7.10.0 or 6.8.14. This issue can be worked around by disabling the emit\_request\_body option in the elasticsearch.yml file.

**CVSSv3 - 1.9:** AV:L/AC:H/PR:H/UI:N/S:U/C:L/I:N/A:N

**CVE ID: CVE-2020-7021**

**Kibana visualization XSS (ESA-2021-04)**

The Kibana “Vega” visualization type is susceptible to both stored and reflected XSS via a vulnerable version of the Vega library. Users who can create these visualizations or craft a vulnerable URL describing this visualization can execute arbitrary JavaScript in the victim’s browser.

**Affected Versions:**

All versions of Kibana before 7.10.2 and 6.8.14 are affected by this flaw

**Solutions and Mitigations:**

Users should upgrade to Kibana version 7.10.2 or 6.8.14. Users unable to upgrade can disable Vega visualizations by setting ‘vega.enabled: false’ in the kibana.yml file.

**CVSSv3 - 8.7:** AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:N

**CVE ID: CVE-2020-26296**
