CVE-2019-14887 is a critical-severity flaw (CVSS 9.1) affecting jboss data grid, jboss enterprise application platform, jboss fuse. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

A flaw was found when an OpenSSL security provider is used with Wildfly, the 'enabled-protocols' value in the Wildfly configuration isn't honored. An attacker could target the traffic sent from Wildfly and downgrade the connection to a weaker version of TLS, potentially breaking the encryption. This could lead to a leak of the data being passed over the network. Wildfly version 7.2.0.GA, 7.2.3.GA and 7.2.5.CR2 are believed to be vulnerable.

redhat jboss data grid DOWNGRADE
Affected: 7.0.0
Fixed in: no fixed release known
Safe to downgrade to: a release before 7.0.0
1. Check installed version
apt-cache policy jboss-data-grid || rpm -q jboss-data-grid || jboss-data-grid --version
2. No fixed release: DOWNGRADE to a release before 7.0.0 (Debian / Ubuntu)
apt-cache madison jboss-data-grid sudo apt install jboss-data-grid=<VERSION_BEFORE_7.0.0> sudo apt-mark hold jboss-data-grid
2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)
