Upstream source description

ToolJet before v3.16.208 fails to validate organizationId ownership in database write and destroy routes, allowing any builder-role user to create, alter, or drop tables in other organizations' databases. Attackers can exploit missing organization-resolving guards to permanently delete tables, insert arbitrary data, and modify schemas across tenant boundaries on shared instances.
