CyberRota Analysis

AI-Generated

The n8n workflow automation platform is vulnerable due to improper handling of user-controlled identifiers in Elasticsearch and ElasticSecurity nodes, allowing attackers to manipulate REST request paths and potentially access unauthorized indices or administrative endpoints. This could lead to data exposure or unauthorized actions within the Elasticsearch environment. Organizations using affected versions prior to 1.123.76, 2.37.7, and 2.38.2 should prioritize updating to mitigate these risks.

Original NVD Description

n8n is an open source workflow automation platform. Prior to 1.123.76, 2.37.7, and 2.38.2, the Elasticsearch and ElasticSecurity nodes interpolated workflow-controlled index and document identifiers directly into REST request paths. An identifier containing path separators or dot segments could select another index or a cluster administration endpoint under the stored Elasticsearch credential. The affected request construction includes packages/nodes-base/nodes/Elastic/Elasticsearch/GenericFunctions.ts and the missing toPathSegment encoding. This issue is fixed in versions 1.123.76, 2.37.7 and 2.38.2.
