Why does anyone running a third party tool have access to all of their clients’ accounts? I can’t imagine something this stupid happening with a real service provider.

I see Vercel is hosted on AWS? Are they hosting every one on a single AWS account with no tenant isolating? Something this dumb could never happen on a real AWS account. Yes I know the internal controls that AWS has (former employee).

Anyone who is hosting a real business on Vercel should have known better.

I have used v0 to build a few admin sites. But I downloaded the artifacts, put in a Docker container and hosted everything in Lambda myself where I controlled the tenant isolation via separate AWS accounts, secrets in Secret Manager and tightly scoped IAM roles, etc.
