CVE-2026-47130Public exploitNetwork attack vector

Cross-tenant data tampering via unchecked object ownership

Published Jul 20, 2026 · Updated Jul 20, 2026

Broken object authorization in NextCRM before 0.12.0 allows remote authenticated users to modify other tenants' contacts and targets. The PATCH handlers for CRM contact and target IDs check only for a session, then update records by URL-supplied ID without matching ownership, assignment, creator, or tenant fields to the session user. A standard member account and another tenant's object UUID are sufficient to overwrite stored CRM data, including contact details and social links.
