Overview

CVE-2026-54306 is a medium-severity vulnerability. It was published on June 23, 2026 and has a CVSS 3.1 base score of 6.4 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 6.4, rated MEDIUM. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

n8n is an open source workflow automation platform. Prior to 2.25.7 and 2.26.2, a prototype pollution vulnerability allowed a crafted public webhook payload to inject attacker-controlled fields into workflow data during internal object copying. These fields could be surfaced and consumed as normal values by downstream built-in nodes. Where a workflow combines a public webhook with action nodes that consume the resulting fields, an attacker could cause the workflow to act as a confused deputy — targeting unintended records or issuing outbound requests using the workflow owner's configured credentials. This vulnerability is fixed in 2.25.7 and 2.26.2.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
