Where to find 'end of life' support info on a samsung phone

Thank you for writing the below post, really helpful, the Easy Installer only covers a limited number of models, your guide will help me if I want to put /e/OS on other models not supported by the Easy Installer.

My Vendor SPL date is 1st Aug 2020.

Looking here:
https://sfirmware.com/samsung-sm-g930f/

I see some later firmwares dated 2021 here:
https://galaxyfirmware.com/model/SM-G930F/XEU/G930FXXU8EUE1
Somehow worked out the CSC Code is XEU (United Kingdom), although I also see other codes quoted such as BTU, VOD, H3G, 02U under ‘Region’, so unsure if they are relevant.

I assume I am advised to be running the most up to date Firmware for my phone.

With my Vendor SPL date of 1st Aug 2020, how at risk are you from malicious attacks.
