How to Fix CVE-2026-54687

To remediate this vulnerability, upgrade all affected N8n nodes sqlite3 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

n8n-nodes-sqlite3 fixed: 1.0.0 
npm install n8n-nodes-sqlite3@1.0.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls n8n-nodes-sqlite3

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2026-54687, inspect your project dependencies using npm:

npm ls n8n-nodes-sqlite3

Analyze the terminal output to locate any version of N8n nodes sqlite3 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.0.0), your application is affected.

Note: The npm ls n8n-nodes-sqlite3 command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In N8n nodes sqlite3, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

## Affected versions < 1.0.0 ## Patched version 1.0.0 ## Description In versions prior to 1.0.0, the SQLite node accepted the database file path as a direct node parameter visible and editable in the workflow. A workflow author who mapped untrusted user input to the db_path field could allow an attacker to control which file was opened by SQLite, potentially enabling path traversal to read or overwrite arbitrary files accessible to the n8n process. The vulnerability requires the workflow author to explicitly wire untrusted input to the db_path parameter, so it does not affect standalone deployments where only trusted users author workflows. However, in multi-tenant or user-facing n8n deployments the risk is elevated. Fixed in v1.0.0 by moving the database path into a credential (v2 node architecture), which is stored server-side and not controllable by workflow input data. ## References - Fix commit: 145a887 - Introduced credential-based path: v2 node ## Credits dyingman1 (role: Reporter)
