Summary

Duplicate Advisory: n8n: External Secrets Accessible via Workflow Expressions Outside Credentials

Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-2434-3x6q-8r99. This link is maintained to preserve external references.

Original Description

n8n before 2.28.1 contains an information disclosure vulnerability where external secrets are incorrectly resolved in workflow node expressions outside credentials scope. Authenticated project editors can read plaintext external secret values by referencing them in node expressions without requiring explicit secrets access permissions.

Severity

6.3 (Medium)

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.
