Hi

I wanted to ask what is the impact of CVE-2020-36518 on Keycloak 15.1.1?  
From the description ([NVD - CVE-2020-36518](https://nvd.nist.gov/vuln/detail/CVE-2020-36518)) is seems to be a serious problem.

We are running Keycloak from docker images, is it a safe workaround to just upgrade (in the Keycloak 15.1.1 image) all of modules in /opt/jboss/keycloak/modules/system/layers/base/com/fasterxml/jackson from version 2.12.1 to 2.13.2?

Thanks in advance.
