AV:A/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:L
HTTP REST API accessible over the network (AV:N); any authenticated user qualifies (PR:L); full cross-tenant read and write constitutes a scope change; A:L reflects table-level destructive capability bounded below full system availability loss.

ToolJet is the open-source foundation am AI-native platform for building and deploying internal tools, workflows and AI agents. Prior to 3.20.207, the ToolJet Database HTTP API in server/src/modules/tooljet-db/controller.ts authorizes operations against the :organizationId URL path value without verifying that the caller belongs to that organization. JwtAuthGuard validates the tj-workspace-id header against the caller's memberships, while server/src/modules/tooljet-db/ability/index.ts grants VIEW_TABLES, VIEW_TABLE, and JOIN_TABLES without binding them to the path organization. An authenticated user can set tj-workspace-id to the user's own workspace and target another workspace through GET /api/tooljet-db/organizations/:organizationId/tables, GET /api/tooljet-db/organizations/:organizationId/table/:tableName, POST /api/tooljet-db/organizations/:organizationId/join, and the related table-management routes, allowing disclosure of table names, schemas, and rows and allowing tables to be created, altered, bulk populated, or dropped across tenant boundaries. This issue is fixed in version 3.20.207-lts.
AnalysisAI
Cross-tenant authorization bypass in ToolJet's Database HTTP API allows authenticated users of any workspace to access and manipulate database tables belonging to other organizations by substituting a victim's organizationId into the URL path. All ToolJet installations prior to version 3.20.207-lts running multi-tenant configurations with the ToolJet Database feature enabled are affected. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must possess a valid ToolJet user account with membership in at least one organization on the target ToolJet instance - no admin or builder role is required; a viewer-level account in any workspace is sufficient. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor-assigned CVSS score of 5.9 with AV:A and PR:H appears to understate real-world risk: the affected endpoints are standard HTTP REST APIs with no documented requirement for adjacent-network positioning, and the description's 'authenticated user' implies PR:L (any valid account holder), not PR:H. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An authenticated ToolJet user with a valid JWT for their own workspace sends a GET request to /api/tooljet-db/organizations/[victim-org-uuid]/tables, setting the tj-workspace-id header to their own workspace ID. The server validates the JWT against the header workspace (their own) and grants VIEW_TABLES without checking whether the URL's organizationId matches the authenticated session - returning the full table listing of the victim organization. … |
| Remediation | The primary fix is to upgrade ToolJet to version 3.20.207-lts or later, released at https://github.com/ToolJet/ToolJet/releases/tag/v3.20.207-lts. … Detailed patch versions, workarounds, and compensating controls in full report. |
