Parameter Value
CVSS 5.3 (MEDIUM)
Affected Versions 2.0.0 — 2.38.2
Fixed In 1.123.76
Type CWE-862 (Missing Authorization)
Vendor N8N
Public PoC No

n8n is an open source workflow automation platform. Prior to 1.123.76, 2.37.7, and 2.38.2, the /rest/active-workflows endpoint returned every active workflow ID on the instance to any member regardless of sharing. Workflow activation, deactivation, and publication push events were also broadcast to clients that could not access the affected workflow, disclosing workflow IDs, version IDs, and activation error details.

The affected paths include packages/cli/src/services/active-workflows.service.ts and packages/cli/src/workflows/workflow-push-notifier.service.ts. This issue is fixed in versions 1.123.76, 2.37.7 and 2.38.2.
