DescriptionCVE.org

ToolJet through 3.0.0-ee-beta.2 contains authorization bypass vulnerabilities in the POST /api/v2/resources/export endpoint that allow authenticated users to disclose TooljetDB table schemas across workspace boundaries and export app definitions across granular permission boundaries. Attackers can supply a body-provided organization_id parameter to access schemas from other workspaces, or bypass per-app authorization gates to export restricted app definitions within their workspace.

AnalysisAI

Cross-workspace authorization bypass in ToolJet through 3.0.0-ee-beta.2 exposes TooljetDB table schemas and restricted app definitions to authenticated low-privilege users via the POST /api/v2/resources/export endpoint. Authenticated users can supply an arbitrary organization_id in the request body to extract database schemas belonging to workspaces they are not members of, and can additionally sidestep per-app granular export permissions within their own workspace to retrieve restricted app definitions. …

Vulnerability AssessmentAI

Exploitation Exploitation requires a valid authenticated ToolJet account at any privilege level (CVSS PR:L confirmed by the provided CVSS 4.0 vector). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 base score of 5.3 (Medium) is reasonable and consistent with the described impact: network-accessible, low-complexity exploitation (AV:N/AC:L/AT:N) requiring a low-privilege authenticated account (PR:L), with limited confidentiality impact on both the vulnerable system and a subsequent system (VC:L/SC:L), and no integrity or availability impact. … 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 The primary remediation is to upgrade ToolJet beyond 3.0.0-ee-beta.2 to a version that enforces server-side workspace membership validation on the POST /api/v2/resources/export endpoint and restores per-app authorization gate checks; consult the vendor advisory at https://github.com/ToolJet/ToolJet/security/advisories/GHSA-pqfh-276q-w3cp to identify the exact patched release version, as it is not independently confirmed from available data. … Detailed patch versions, workarounds, and compensating controls in full report.
