What is CVE-2026-48150?

Budibase, an open-source low-code platform, contains a vulnerability that allows workspace-scoped builders to escalate their privileges to global admin. This occurs when the /api/public/v1/roles/assign endpoint, which should be adequately protected, fails to differentiate between workspace and global builders. As a consequence, users with an Enterprise license can exploit the vulnerability to promote themselves or any user to global admin status through a single API call. The issue is resolved in version 3.39.0, emphasizing the importance of upgrading to maintain security.
