CVE-2026-82874

CVSS 9.9 (critical) · published 2026-08-31

ToolJet before v3.16.208 fails to validate that authenticated users belong to the organization specified in the organizationId path parameter of tooljet-db endpoints, allowing any Builder user to read, modify, and delete tables across tenant boundaries. Attackers can extract victim organization IDs from public app endpoints, then exploit schema operation endpoints to disclose table schemas, plant malicious tables, corrupt existing schemas, or permanently destroy victim data without any relationship to the target organization.
