Budibase server version 3.39.4 contains an authorization regression in the S3 presigned URL upload endpoint. This flaw allows BASIC app users, who normally have limited permissions, to obtain S3 PutObject presigned URLs. The endpoint incorrectly uses TABLE/WRITE permission instead of the intended BUILDER level, and does not restrict the target S3 bucket to the configured datasource bucket, enabling uploads to any S3 bucket accessible by the stored IAM credentials.
