Name of the Vulnerable Software and Affected Versions Budibase versions prior to 3.38.1

Description An issue exists in the "POST /api/global/users/onboard" endpoint, which is protected by the workspaceBuilderOrAdmin middleware. This allows users with builder permissions to access the endpoint. In self-hosted instances where SMTP email is not configured, the endpoint bypasses the standard admin-restricted invite flow and uses the bulkCreate function to create users directly. Because the request body accepts arbitrary admin and builder role assignments, a builder-level user can create a new global admin account. The system then returns the generated password in the response, leading to full privilege escalation and platform compromise.

Recommendations Update to version 3.38.1. As a temporary workaround, restrict access to the "POST /api/global/users/onboard" endpoint to only authorized administrators.
