What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

n8n before 1.123.85, 2.43.5, and 2.44.1 contains an authorization bypass vulnerability that allows authenticated members to use inaccessible credentials through inline sub-workflow nodes with non-boolean disabled values. Attackers knowing a credential id can run Execute Workflow nodes in inline JSON mode that skip the permission check and send decrypted credentials to attacker-controlled servers.
