In our multi store magento we have many blocks which some are disabled. Is there any way that provides the list of blocks which need to be added to white list instead of going through all cms blocks one by one?
Please find How to check which modules are affected by security patch SUPEE-6788 and check the introduced community tools. I used https://github.com/peterjaap/magerun-addons to get a list of used block vars. Use
n98-magerun dev:template-var to get the needed list.
Another approach is https://github.com/rhoerr/supee-6788-toolbox. It is a shell script to search all used block vars.
