Summary
Duplicate Advisory: Custom Header Credential Values Leaked in Plaintext into LLM Node Execution Data
Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-89gh-3pgc-v5h2. This link is maintained to preserve external references.

Original Description

n8n versions before 1.123.64 fail to properly mask custom HTTP header credentials in LLM sub-node execution data, writing plaintext API keys and secrets to workflow execution records. Authenticated users with access to execution data can read exposed header values and credentials that persist in the database and can be exported.
