CVE-2026-45716 Details
Description
Budibase is an open-source low-code platform. Prior to 3.38.1, 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. This vulnerability is fixed in 3.38.1.
A privilege escalation vulnerability has been identified in Budibase, an open-source low-code platform, in versions prior to 3.38.1. The issue arises in the POST /api/global/users/onboard endpoint, which is accessible to users with builder permissions. When SMTP email is not configured, this endpoint bypasses the admin-only invite process and allows for the direct creation of users with arbitrary admin and builder role assignments. A builder-level user can exploit this to create a global admin account, receiving the generated password in response, thus achieving full privilege escalation.
Users can update to Budibase version 3.38.1 or later, where this vulnerability has been fixed.
