CVE-2026-82874Public exploitNetwork attack vectorHinoki check available

Cross-tenant data compromise via unchecked organizationId

Published Aug 31, 2026 · Updated Aug 31, 2026

Authorization bypass in ToolJet before 3.16.208 allows remote authenticated users to read, alter, and delete other tenants' tables. The tooljet-db controller passes the organizationId path parameter to table operations while its ability guard checks only the client-controlled tj-workspace-id header, without verifying membership in the path-selected organization. A Builder account in any organization and a victim organization ID are sufficient to disclose schemas, corrupt structures, plant tables, or permanently delete victim tables.
