Vulnerability CVE-2020-13956 reported on Elasticsearch 7.17.4


vulnerability CVE-2020-13956 is reported on the httpclient-4.5.10.jar libraries of the reindex module of Elasticsearch (modules/reindex/httpclient-4.5.10.jar).

Are there any official statements regarding if this vulnerability does indeed apply to Elasticsearch 7.17.4, or any plan to upgrade httpclient to a version that does not have the vulnerability ?

If not, is there any way that I can help upgrading this dependency to a higher version ?

Thanks for your help on this.
