Firebase is a shitshow. I say this as someone who really tried to like it and sadly built a project for a client using it. Other than this security vuln, the issues vs. just using postgres are: * It is more work! Despite being a backend as a service it is much less code to just write a simple API backend for your thing both in time to do it and time to learn how to do it. Think of Firebase as being on the abstraction…
EDIT:
loud buzzer
Careful, Icarus: "permissions can be setup to allow global read-writes" is a "vuln" of every system.
p.s. Any comment on why her blog has you guys "remembering Chattr" then getting a seedy Firebase pwner GUI, and yours has you diligently looking through .ai TLDs?
