CVE-2026-26745Public exploitNetwork attack vector

Database disclosure via stored currency-symbol SQL injection

Published Feb 20, 2026 · Updated Feb 20, 2026

Second-order SQL injection in OpenSourcePOS 3.4.1 allows remote authenticated users to read database data via a stored currency symbol. Summary_discounts::getData retrieves currency_symbol from global configuration and concatenates it unescaped into a Query Builder select expression. An account with configuration-change permission can store a payload, and generation of the Summary Discounts report later executes it for time-based extraction.
