The CVE-2025-XXXX vulnerability in Ibexa eZ Platform’s Admin UI assets allows stored Cross-Site Scripting (XSS) attacks in the back office. Attackers with Editor or Administrator privileges can inject malicious JavaScript payloads into various admin interface components. These payloads persist and execute when other privileged users access the compromised sections. The vulnerability arises due to insufficient input sanitization in the Admin UI asset handling, allowing script injection that reflects in both back-office and front-office views.
