I am looking into upgrading Erlang 24.2 (which is affected by CVE-2022-37026) in an on prem Outsystems 11.18.1 setup. In order to determine the steps to be taken, I looked at the cache invalidation service requirements and saw that our current setup is the minimum required versionfor both RabbitMQ and Erlang (v3.9.11 and v24.2). I noticed that these versions can be upgraded to the latest minor version compliant with the official documentation, however I did not find the assurance that upgrading RabbitMQ from v3.9.11 to v3.9.22 and Erlang v24.2 to Erlang v24.3.4.2 will work properly with our Outsystems Platform Server v11.18.1.
I have received confirmation that this is possible.
