n8n: Arbitrary File Read via Git Node

n8n is an open source workflow automation platform. Prior to 1.123.43, 2.22.1, and 2.20.7, an authenticated user with permission to create or modify workflows could inject CLI flags on the Git node's Push operation allowing an attacker to read arbitrary files from the n8n server potentially leading to full compromise. This vulnerability is fixed in 1.123.43, 2.22.1, and 2.20.7.
