The CVE-2025-XXXXX vulnerability is a persistent Cross-Site Scripting (XSS) flaw within the Ibexa DXP admin UI. It specifically exists in the modal dialog used for canceling or rescheduling future content publications. The vulnerability arises because user-supplied input, such as image asset names and content language names, is not properly sanitized before being rendered in this modal. An attacker with editor-level permissions or higher can craft a malicious payload and inject it into one of these fields. When an administrator or another privileged user views the modal, the malicious JavaScript code is executed within their browser session. This allows the attacker to perform actions with the permissions of the targeted user, potentially leading to session hijacking, unauthorized content changes, or account takeover. The same injected script could also be reflected on the public-facing front office, impacting end-users.
