CVE-2026-54302CVE-2026-54302

n8n / n8n

Description

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.
