CVE-2026-59109 Detail

Description

SQL injection in the Zalktis accounting application via trading-partner-controlled text fields in received electronic invoices. When importing a received e-invoice (UBL/PEPPOL) or an e-commerce export, Zalktis concatenates partner-controlled values directly into SQL statement text using string concatenation, with neither parameterised queries nor escaping. The application's own escaping helper, Dazadi.sql_txt(), is not invoked on these code paths, so a party that sends an invoice can break out of the string literal and alter the query logic. This issue affects Zalktis: before 2026.1.586 and before 2026.2.592.
