Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

How this class of weakness works · CWE-79

Untrusted input is placed into a web page without being neutralised, so an attacker's markup or script executes in another user's browser. That can hijack sessions, capture keystrokes, or silently perform actions as the victim. Fixing it properly means context-aware output encoding everywhere data meets HTML, backed by a content-security policy as a second line of defence.

Recommended fix High confidence

1.114.0

  1. 1. Back up your current n8n instance, including workflow data, credentials, and configuration files.
  2. 2. For Docker installations: Run `docker pull n8nio/n8n:1.114.0` to pull the fixed version image.
  3. 3. For Docker installations: Stop and remove the existing container, then recreate it with the new image using your original startup command.
  4. 4. For npm installations: Run `npm install -g [email protected]` to install the patched version.
  5. 5. For manual installations: Download version 1.114.0 from the official n8n releases page and replace the existing installation files.
  6. 6. Restart the n8n service to apply the update.
  7. 7. Verify the upgrade was successful by checking the n8n version in the UI or via command line.
  8. 8. Test the 'Respond to Webhook' node functionality to confirm the XSS protection is working as expected.
Caveat No breaking changes specifically mentioned in the advisory; upgrade is recommended to patch the XSS vulnerability.
