Basically, folder permissions never let anyone allows to directly write files but EE’s folder permission had been set to “Everyone:(OI)(CI)(F)”.

This permission allows any user can read, write, execute, create, delete do anything inside that folder and its subfolders.

When he analyzed the subfolders and find that  ACL rules set as “OI – Object Inherit” and “CI – Container Inherit” which means that it’s subfolder also have full permission.
