## Technical details

The vulnerability is a Cross-Site Request Forgery (CSRF) vulnerability in express-cart versions up to 1.1.10. The root cause is that the admin API endpoints only validate session cookies without implementing CSRF tokens, allowing an attacker to craft a malicious HTML form that, when visited by an authenticated admin, performs unwanted state-changing actions. The attack vector is network-based and requires user interaction (the admin must visit the attacker's page while logged into express-cart). An attacker can exploit this to create discount codes, modify settings, or perform other admin-level operations. The vulnerability was fixed in version 1.1.17.
