Official description
Hulumi is an open-source toolkit that ships secure-by-default cloud and platform infrastructure components for Pulumi. Prior to version 1.4.0, consumers using AccountFoundation could ship an AWS account whose CloudTrail / Config audit logs were deletable by any S3-delete-capable principal — while believing the startup-hardened tier guaranteed tamper-resistance. Sandbox-tier deployments had no audit immutability at all (defects 1 and 3 compounded). This issue has been patched in version 1.4.0.
