CVE-2021-44832 is not really a vulnerability.
1. It is an Arbitrary Code Execution (ACE), not a Remote Code Execution (RCE)
1. It can be only triggered by changing the config file
1. If 2. is already the case, then you have a bigger problem (misconfiguration of your application and system)
1. It is not a vulnerability (that you have to care about) by definition
1. There is more hype and drama than really needed and justified
