CVE-2026-54302 · n8n: Stored XSS in Chat Trigger Node

This page contains facts from public vulnerability sources. Check the original advisory before updating.

n8n is an open source workflow automation platform. Prior to 1.123.55, 2.25.7, and 2.26.2, an authenticated user with workflow edit access could inject arbitrary JavaScript into the Chat Trigger's generated page by setting a malicious webhookId. When a logged-in user visited the chat URL, the injected code executed in the n8n origin with that user's session privileges. This vulnerability is fixed in 1.123.55, 2.25.7, and 2.26.2.
