# CVE-2026-34036

> 6.5 MEDIUM · 🧪 PoC

## Beschreibung

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. By manipulating the objectdesc parameter and exploiting a fail-open logic flaw in the core access control function restrictedArea(), an authenticated user with no specific privileges can read the contents of arbitrary non-PHP files on the server (such as .env, .htaccess, configuration backups, or logs…). At time of publication, there are no publicly available patches.
