CVE-2026-86077
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.
