CVE-2026-86074 - n8n: Instance AI Credential Setup Accepts Unvalidated Probe URL from Fetched Content
CVE ID :CVE-2026-86074
Published : Sept. 8, 2026, 6:21 p.m. | 44 minutes ago
Description :n8n is an open source workflow automation platform. Prior to 2.37.7 and 2.38.2, the Instance AI credential setup flow accepted a credential test or verification URL without checking that it matched the workflow node's origin. Attacker-controlled fetched content could influence that URL after a user injected it into the setup flow, causing authenticated requests, redirects, or probes to reach another origin. The affected logic includes packages/@n8n/instance-ai/src/tools/workflows/credential-utils.ts and the extractServiceOrigin origin derivation. This issue is fixed in versions 2.37.7 and 2.38.2.
Severity: 5.9 | MEDIUM
