Technical details

A stored cross-site scripting (XSS) vulnerability exists in the item title field of FairSketch Rise CRM versions up to 3.9.6. An authenticated administrator can inject arbitrary JavaScript payload (e.g., <img src=x onerror=alert(document.cookie)>) via the /index.php/items edit interface, which is persisted server-side. When any authenticated client user navigates to /index.php/store to view items, the malicious script executes in their browser context with their privileges. This allows an attacker to exfiltrate session cookies, perform unauthorized actions, or redirect users to phishing pages. The vulnerability was fixed in version 4.0 through input validation. The attack requires an authenticated admin account but affects all client users who view the store.
