CVE-2026-59109Public exploitNetwork attack vector

SQL injection via unescaped imported invoice fields

Published Aug 13, 2026 · Updated Aug 13, 2026

SQL injection in Zalktis before 2026.1.586 and before 2026.2.592 allows remote attackers to alter accounting queries via imported invoices. During UBL/PEPPOL e-invoice or e-commerce export import, affected paths concatenate partner-controlled text into SQL without parameterization or escaping and omit the Dazadi.sql_txt() helper. Exploitation requires a user to import a sender-controlled document, after which injected text can break out of a string literal and change query logic.
