CVE-2026-34036
Dolibarr Core Discloses Sensitive Data via Authenticated Local File Inclusion in selectobject.php

Dolibarr is an enterprise resource planning (ERP) and customer relationship management (CRM) software package. In versions 22.0.4 and prior, there is a Local File Inclusion (LFI) vulnerability in the core AJAX endpoint /core/ajax/selectobject.php.
