CVE-2026-26745: Opensourcepos Open Source Point Of Sale

Medium severity, CVSS 5.3. EPSS: 0.4% chance of exploitation in the next 30 days.

OpenSourcePOS 3.4.1 has a second order SQL Injection vulnerability in the handling of the currency_symbol configuration field. Although the input is initially stored without immediate execution, it is later concatenated into a dynamically constructed SQL query without proper sanitization or parameter binding. This allows an attacker with access to modify the currency_symbol value to inject arbitrary SQL expressions, which are executed when the affected query is subsequently processed.
