CVE-2026-25052
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 · uneditedn8n 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.
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.
dbcve analysis · high confidenceA path traversal vulnerability in n8n's file access controls allows authenticated users with workflow create/modify permissions to read arbitrary files from the host system, exposing configuration files and user credentials that enable complete account takeover.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the installed n8n versionRun `n8n --version` from the command line, check the Docker image tag, or look in package.json if self-hostedAffected if The version is less than 1.123.18 OR greater than or equal to 2.0.0 but less than 2.5.0
-
Verify workflow create/modify permissions existCheck user roles and permissions in n8n admin panel under Users or Roles settings, or query the database for users with workflow create or workflow edit privilegesAffected if Any user role includes workflow create or workflow modify permissions (not limited to admin-only)
-
Check if file operation nodes are availableLook for enabled nodes related to file operations in n8n (e.g., Read Binary File, Write Binary File, or similar file-related nodes) under Settings > Nodes or in the workflow editor node listAffected if File operation nodes are enabled and accessible to users with workflow permissions
-
Inspect file access configuration settingsCheck n8n configuration files (config.yaml or environment variables) for settings related to file access, such as allowed directories or file node permissionsAffected if File access is not restricted to safe directories or file node execution is permitted for non-admin users
You are affected if your n8n version falls in the vulnerable range AND non-admin users have workflow create/modify permissions AND file operation features are accessible to them.

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.
dbcve · scoped1.123.182.5.0
Upgrade n8n to version 1.123.18 or 2.5.0 or later to patch the arbitrary file read vulnerability.
n8n version 1.123.18 or 2.5.0
- 1. Backup your n8n database and configuration files before upgrading
- 2. Stop the n8n service to prevent data corruption during upgrade
- 3. Upgrade n8n to version 1.123.18 (if staying on 1.x branch) or version 2.5.0 (if moving to 2.x branch)
- 4. Verify the upgrade completed successfully by checking the n8n version after restart
- 5. Restart the n8n service
- 6. Test that workflows function correctly after the upgrade
