Title
n8n before 1.123.83 Authorization Bypass via Execute Sub-workflow Inline JSON
Summary
n8n before 1.123.83 contains an authorization bypass vulnerability that allows authenticated members to spoof workflow identity by supplying a trusted identifier in Execute Sub-workflow inline JSON mode. Attackers can set this identifier to resolve credentials from projects they do not belong to and modify another workflow's static data and error-workflow dispatch.
