CVE-2026-32888: Opensourcepos Open Source Point Of Sale

High severity, CVSS 8.8. EPSS: 0.5% chance of exploitation in the next 30 days.

Open Source Point of Sale is a web based point-of-sale application written in PHP using CodeIgniter framework. Versions contain an SQL Injection in the Items search functionality. When the custom attribute search feature is enabled (search_custom filter), user-supplied input from the search GET parameter is interpolated directly into a HAVING clause without parameterization or sanitization. This allows an authenticated attacker with basic item search permissions to execute arbitrary SQL queries. A patch did not exist at the time of publication.
