    Am I affected by n8n: Public API Execution Retry Authorization Bypass? What should I do?

    The Public API endpoint for retrying executions authorized access using workflow:read rather than workflow:execute.

    Affected: n8n < 2.25.7 and 2.26.0 to 2.26.2. Fixed in: 2.25.7 and 2.26.2. What should you check, and what should you do about it?

      Am I affected? Affected: n8n < 2.25.7 and 2.26.0 to 2.26.2. Fixed in: 2.25.7 and 2.26.2.

      • Check your version: run npm ls n8n. Versions >= 2.26.0, < 2.26.2 of n8n are affected.

      What to do now

      1. Upgrade to the fixed version: run npm install n8n@2.26.2 (first patched version 2.26.2).
      2. Upgrade to n8n 2.25.7 or 2.26.2, or later.
      3. If upgrading is not immediately possible, restrict workflow sharing to fully trusted users only.
      4. Restrict network access to the n8n Public API to trusted users only.

      General practice, not from the source: if the affected software could read tokens or credentials, rotate them after upgrading; pin versions and review changes before updating tools your agents run.
