NVD description
n8n is an open source workflow automation platform. Prior to versions 1.123.18 and 2.5.0, a vulnerability in the file access controls allows authenticated users with permission to create or modify workflows to read sensitive files from the n8n host system. This can be exploited to obtain critical configuration data and user credentials, leading to complete account takeover of any user on the instance. This issue has been patched in versions 1.123.18 and 2.5.0.
What to do
- Upgrade n8n to
1.123.18or later (or the patched release of your branch: 2.5.0). - Do not expose the component's API or UI to the internet without authentication in front of it.
