CyberRota Analysis
AI-GeneratedThe vulnerability allows unauthenticated users to cancel active test webhook registrations for specific workflows in n8n versions prior to 2.28.0 and 2.27.4 on the 2.27.x branch. While the impact is primarily limited to disrupting ongoing test sessions, it poses a risk to developers relying on these tests for workflow validation. Organizations using affected versions should prioritize patching to maintain the integrity of their testing processes.

Original NVD Description
n8n before 2.28.0 (and before 2.27.4 on the 2.27.x branch) registers the DELETE /${restEndpoint}/test-webhook/:id endpoint before authentication middleware is applied, allowing any unauthenticated network caller who knows a workflow ID to cancel that workflow's active test webhook registration. The impact is limited to disrupting in-progress test sessions; production webhooks, persistent workflow state, and stored data are not affected.
