Description

n8n is a workflow automation platform. From 1.77.0 to before 1.98.2, a stored Cross-Site Scripting (XSS) vulnerability was identified in n8n, specifically in the Form Trigger nodes HTML form element. An authenticated attacker can inject malicious HTML via an with a srcdoc payload that includes arbitrary JavaScript execution. The attacker can also inject malicious Javascript by using <video> coupled <source> using an onerror event. While using iframe or a combination of video and source tag, this vulnerability allows for Account Takeover (ATO) by exfiltrating n8n-browserId and session cookies from authenticated users who visit a maliciously crafted form. Using these tokens and cookies, an attacker can impersonate the victim and change account details such as email addresses, enabling full control over the account—especially if 2FA is not enabled. Users should upgrade to version >= 1.98.2.</p> </div> </div> </div> </div> </div> </div> </div> <footer> <div class="container py-4 py-lg-10"> <hr> <div class="text-muted d-flex justify-content-between align-items-center pt-3" style="text-align: center;"> <p class="mb-10"><center>Copyright © 2026 eXtreme Hosting</center></p> <p class="mb-10"><center><a href="/gdpr/">Privacy Policy GDPR/AVG</a> | <a href="/algemene-voorwaarden/">Algemene voorwaarden</a></center></p> </div> </div> </footer> <script src="/template/assets/bootstrap/js/bootstrap.min.js"></script> <script src="/template/assets/js/startup-modern.js"></script> </body> </html><img style="display: none;" src="https://telemetry.extremehosting.nl/Analy/?api=0C44A78F-C43E-4700-990A-0F40CE4B4A51&dtt=1746954019&urr=https://extremehosting.nl/cve/cve-details/CVE-2025-52478" />
