Description

n8n before 1.123.85, 2.43.5, and 2.44.1 contains a credential guard bypass vulnerability that allows editors of shared workflows to use restricted credentials by loading sub-workflows from URLs or local files. Attackers can configure the Execute Sub-workflow node with source url or localFile to serve content that resolves project credentials and returns their decrypted values.
