CVE-2026-45716— Budibase 安全漏洞

Budibase: Builder-to-Admin Privilege Escalation via onboardUsers Endpoint Without SMTP Configuration

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.

特权管理不恰当

Budibase 安全漏洞

Budibase是英国Budibase开源的一个用于在几分钟内创建内部应用程序、工作流和管理面板的低代码平台。 Budibase 3.38.1之前版本存在安全漏洞，该漏洞源于POST /api/global/users/onboard端点受workspaceBuilderOrAdmin中间件保护且未配置SMTP时绕过管理员限制的邀请流程直接创建用户，可能导致构建者级别用户创建全局管理员账户实现权限提升。
