CyberRota Analysis
AI-GeneratedThe vulnerability in n8n allows an attacker with access to a resumeToken to exploit the /chat WebSocket route, potentially resuming paused executions without proper authorization checks. This could lead to unauthorized execution of non-chat tasks, impacting workflow integrity and security. Organizations using n8n versions prior to 2.37.7 and 2.38.2 should prioritize updating to mitigate the risk of unauthorized access and execution.

Original NVD Description
n8n is an open source workflow automation platform. Prior to 2.37.7 and 2.38.2, the /chat WebSocket route accepted a resumeToken and resumed a paused execution without checking that the target node supported chat messages. An anonymous form submitter who received that token could reuse it on the chat route to release a Send-and-Wait, non-chat HITL, or Wait approval gate. The affected authorization logic is packages/cli/src/chat/chat-execution-manager.ts, where canResumeOverChat did not gate the resume target. This issue is fixed in versions 2.37.7 and 2.38.2.
