Overview
@budibase/server is a Budibase Web Server
Affected versions of this package are vulnerable to Missing Authorization via the getSignedUploadURL process. An attacker can gain unauthorized access to generate AWS S3 pre-signed PUT URLs using stored IAM credentials by sending unauthenticated requests to the affected endpoint with attacker-controlled parameters. This allows arbitrary file uploads to any bucket accessible by the IAM credentials, potentially leading to data exposure, data tampering, or resource exhaustion.
