CVE-2026-42226— n8n 安全漏洞

n8n: Credential Authorization Bypass in dynamic-node-parameters Allows Foreign API Key Replay

n8n is an open source workflow automation platform. Prior to versions 1.123.33 and 2.17.5, the dynamic-node-parameters endpoints did not verify whether the authenticated caller was authorized to use a supplied credential reference. An authenticated user with access to a shared workflow could supply a foreign credential ID in the request body, causing the backend to decrypt and use that credential in a helper execution path where the caller also controls the destination URL. This allowed the caller to force the backend to authenticate against attacker-controlled infrastructure using a credential belonging to another user, effectively exfiltrating a reusable API key. The issue is not limited to any single node type; any node that resolves credentials dynamically through these endpoints may be affected. This issue has been patched in versions 1.123.33, 2.17.5, and 2.18.0.

n8n 安全漏洞

n8n是n8n开源的一个可扩展的工作流自动化工具。 n8n 1.123.33之前版本、2.17.5之前版本和2.18.0之前版本存在安全漏洞，该漏洞源于动态节点参数端点未验证认证调用者是否有权使用提供的凭据引用，可能导致认证用户强制后端使用其他用户的凭据向攻击者控制的基础设施进行身份验证。
