Summary

Affected are n8n versions from 0 before 1.123.85, from 2.0.0 before 2.43.5, and from 2.44.0 before 2.44.1. A credential guard bypass in the Execute Sub-workflow node lets editors of shared workflows use restricted credentials by loading sub-workflows from URLs or local files (CWE-863). An attacker with editor access to a shared workflow can obtain decrypted project credentials, and no user interaction is needed.
