CVE-2021-22997
On all 7.x and 6.x versions (fixed in 8.0.0), BIG-IQ HA ElasticSearch service does not implement any form of authentication for the clustering transport services, and all data used by ElasticSearch for transport is unencrypted.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.07%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
