Technical details

A stored cross-site scripting (XSS) vulnerability exists in Open Source Point of Sale (OSPOS) due to improper output encoding in the Daily Sales management table. Specifically, the 'customer_name' column in the bootstrap-table configuration is explicitly set to 'escape: false' within 'app/Helpers/tabular_helper.php', causing the application to render customer names as raw HTML. An attacker with low-level customer management privileges can inject a malicious payload into the 'first_name' or 'last_name' fields. When a victim (such as an administrator) views the Daily Sales page (/sales/manage), the payload executes in their browser context. While HttpOnly flags protect session cookies, an attacker can still perform CSRF-based actions or exfiltrate page content. The issue is resolved in version 3.4.3 by removing 'customer_name' from the escape exception regex.
