Description

n8n is an open source workflow automation platform. Prior to version 1.114.0, a stored Cross-Site Scripting (XSS) vulnerability may occur in n8n when using the “Respond to Webhook” node. When this node responds with HTML content containing executable scripts, the payload may execute directly in the top-level window, rather than within the expected sandbox introduced in version 1.103.0. This behavior can enable a malicious actor with workflow creation permissions to execute arbitrary JavaScript in the context of the n8n editor interface. This issue has been patched in version 1.114.0. Workarounds for this issue involve restricting workflow creation and modification privileges to trusted users only, avoiding use of untrusted HTML responses in the “Respond to Webhook” node, and using an external reverse proxy or HTML sanitizer to filter responses that include executable scripts.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for n8n. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update n8n to 1.114.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-61914 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 pinpoints whether CVE-2025-61914 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to CVE-2025-61914. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
