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 before 2.32.1 (and before 2.31.5) is vulnerable to account takeover via the Token Exchange Embed Login feature. When a validly-signed incoming token was matched to a local account by its email claim, the service did not verify that the email claim was verified, nor that the trusted key's permitted role ceiling covered that account. As a result, anyone able to obtain a token accepted by a configured trusted key (for example, a trusted issuer emitting unverified email addresses) could authenticate as any existing user and gain full account control. This issue only affects instances where the embed login feature is enabled and at least one trusted key source is configured.

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.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Recommended fix High confidence

n8n version 2.32.1 (or 2.31.5 as minimum)

  1. 1. Check current n8n version by running `n8n --version` or checking the container/service version
  2. 2. If running a version before 2.31.5 or between 2.31.5 and 2.32.0, plan the upgrade
  3. 3. Back up the n8n database and configuration files before upgrading
  4. 4. Upgrade n8n to version 2.32.1 (or at minimum 2.31.5) following your deployment method (Docker, npm, etc.)
  5. 5. After upgrade, verify the embed login feature still functions correctly
  6. 6. Review trusted key source configurations to ensure they properly validate email claims and role ceilings
