CVE-2026-118642
n8n before 1.123.85, 2.43.5, and 2.44.1 Credential Permission Check Bypass via Inline Sub-Workflows
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.
