CVE-2026-73301
Budibase: Missing RBAC on GET /api/global/groups allows BASIC users to enumerate all tenant groups and role mappings
Impact
Budibase is an open-source low-code platform. Prior to 3.39.25, the GET /api/global/groups endpoint in packages/worker/src/api/routes/global/groups.ts omitted auth.builderOrAdmin, allowing an authenticated BASIC role user to enumerate tenant groups, role mappings and user memberships, builder permissions, and default-group flags. The disclosure exposes the tenant access-control structure to users who are not builders or administrators. This issue is fixed in version 3.39.25.
