ToolJet before v3.16.208 fails to validate organization membership in database read routes, allowing any authenticated user to access other organizations' table schemas and row data. Attackers can supply arbitrary organization IDs in URL parameters to list tables, retrieve column definitions, and execute join queries to read actual stored data from victim organizations.
AnalysisAI
Cross-organization data exposure in ToolJet before v3.16.208 allows any authenticated user to read table schemas and row data belonging to other tenant organizations by supplying arbitrary organization IDs in URL parameters to database read routes. The flaw represents a complete collapse of multi-tenant isolation: attackers can enumerate tables, retrieve column definitions, and execute join queries against victim organization data without triggering any authorization error. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid authenticated ToolJet session; any low-privilege user account within the shared instance is sufficient (PR:L per CVSS). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 8.2 reflects high confidentiality impact against both the vulnerable system and subsequent (cross-tenant) systems, with low complexity and low privilege requirements - the dominant risk is complete cross-tenant data theft. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade to ToolJet v3.16.208 or later immediately; this release adds organization membership validation on all database read routes and is the authoritative fix per the vendor advisory at https://github.com/ToolJet/ToolJet/security/advisories/GHSA-xqqj-pfc2-vf48. … Detailed patch versions, workarounds, and compensating controls in full report. |
