Vulnerability from github – Published: 2026-02-04 20:33 – Updated: 2026-02-06 21:43

Summary

n8n's domain allowlist bypass enables credential exfiltration

Details

Impact

A vulnerability in the HTTP Request node's credential domain validation allowed an authenticated attacker to send requests with credentials to unintended domains, potentially leading to credential exfiltration.

This only might affect user who have credentials that use wildcard domain patterns (e.g., *.example.com) in the "Allowed domains" setting.

Patches

This issue is fixed in version 1.121.0 and later. All users are strongly encouraged to upgrade.

Workarounds

Until projects can upgrade:

Replace wildcard domain patterns with explicit domain listings in HTTP Request credentials
Review and restrict workflow creation/modification permissions to trusted users only
Audit existing workflows using HTTP Request nodes with domain-restricted credentials

n8n has adopted CVSS 4.0 as primary score for all security advisories. CVSS 3.1 vector strings are provided for backward compatibility.

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
