CVE-2023-33568Public exploitNetwork attack vector

Customer data disclosure via wildcard contact lookup

Published Jun 13, 2023 · Updated Jan 3, 2025

Information disclosure in Dolibarr ERP CRM 16.0.0 through 16.0.4 allows remote attackers to retrieve contact records without authentication. The public ticket AJAX endpoint handles action=getContacts by placing the email parameter in a SQL LIKE lookup, so a percent wildcard matches every stored contact. The endpoint requires the Ticket module and its contact-creation option to be enabled, and one request exposes customer, prospect, supplier, employee, and private-note data.
