CVE-2026-8218Public exploitNetwork attack vector

Browser script execution via unneutralized purchase-return input

Published May 10, 2026 · Updated May 10, 2026

Cross-site scripting in Devs Palace ERP Online 4.0.0 and earlier allows remote authenticated users to inject scripts via a purchase-return request. The /inventory/purchase_return_save endpoint places attacker-controlled input into browser-rendered output without neutralizing executable content. Exploitation requires high-privilege access and user interaction; the demonstrated consequence is modification of content within the application origin.
