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.

Attack-Flow Graph

Executive Summary

This vulnerability exists in the n8n workflow automation platform prior to versions 1.123.18 and 2.5.0. It involves improper file access controls that allow authenticated users who have permission to create or modify workflows to read sensitive files on the host system where n8n is running.

By exploiting this flaw, an attacker can obtain critical configuration data and user credentials stored on the host, which can lead to a complete takeover of any user account on the n8n instance.

This vulnerability has been fixed in versions 1.123.18 and 2.5.0.

Impact Analysis

If exploited, this vulnerability can allow an attacker with workflow creation or modification permissions to access sensitive files on the n8n host system.

This can lead to exposure of critical configuration data and user credentials.

Ultimately, this can result in a complete account takeover of any user on the n8n instance, potentially compromising the entire system and its workflows.
