Improper Privilege Management

CVE-2026-45716

Low
0/10

Summary

The `POST /api/global/users/onboard` endpoint is protected by `workspaceBuilderOrAdmin` middleware, allowing any user with builder permissions to access it. When SMTP email is not configured (the default for self-hosted Budibase instances), this endpoint bypasses the admin-restricted invite flow and directly creates users via `bulkCreate`, accepting arbitrary `admin` and `builder` role assignments from the request body. A builder-level user can create a new global admin account and receive the generated password in the response, achieving full privilege escalation. The affected versions are prior to 3.38.1.

CWE-269 - Improper Privilege Management

An effective privilege management infrastructure provides valid users with required access and privileges across heterogeneous technology environments. An application with a faulty privilege management infrastructure allows higher than authorized privileges or enables privilege escalation. This can lead to security incidents such as system infiltration, data breach, and complete system takeover.
