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

Quick assessment

Affected

n8n-io n8n

Exploitation

No confirmed in-the-wild exploitation; assess based on exposure

Recommended action

Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

n8n 在 1.123.85、2.43.5 和 2.44.1 之前的版本中存在一个授权绕过漏洞。该漏洞允许已认证的用户通过内联子工作流节点中非布尔类型的“禁用”值，使用本应无法访问的凭据。若攻击者知晓某个凭据 ID，便可在内联 JSON 模式下运行“执行工作流”（Execute Workflow）节点，从而绕过权限检查，并将已解密的凭据发送至由攻击者控制的服务器。

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

Source: CVE Program / CVE List V5

Vulnerability 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.
