ToolJet Workspace Isolation Bypass in Database Operations

ToolJet before v3.16.208 fails to validate that the path organizationId matches the authenticated user's workspace before performing ToolJet DB table operations. A workspace admin can create, view, and delete database tables in another workspace by replacing the organizationId parameter in table-management API requests.

Casky was already ahead

This CVE exploits attack patterns that Casky's 283matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

ToolJet versions before 3.16.208 contain a critical authorization flaw where the platform fails to validate that an authenticated user's organizationId matches their actual workspace before executing database table operations. This vulnerability allows a workspace admin to manipulate API requests by substituting organizationId parameters to gain unauthorized access to tables in other workspaces—enabling cross-workspace data creation, viewing, and deletion. With a CVSS score of 9.1, this represents a severe breach of multi-tenant isolation, affecting all ToolJet deployments where administrators could exploit horizontal privilege escalation to compromise other organizations' data integrity and confidentiality.

Casky's 283 matching skills detect the attack patterns behind this vulnerability by mapping to MITRE ATT&CK techniques TA0004 (Privilege Escalation) and TA0006 (Credential Access). Practitioners using Casky's Claude-powered analysis would identify lateral movement indicators such as: API requests with mismatched organizationId parameters originating from authenticated admin accounts, database table operations (CREATE/READ/DELETE) executing outside the user's authorized workspace scope, and audit logs showing cross-organization resource access from single sessions. The platform's extended reasoning capabilities correlate these signals with CWE-639 (Authorization Bypass Through User-Controlled Key) patterns, surfacing findings that reveal how attackers exploit insufficient access control validation—enabling security teams to prioritize remediation, implement workspace boundary enforcement, and audit historical access logs for unauthorized cross-workspace operations.
