Vulnerability Title
n8n before 1.123.64 Stored DOM XSS via cachedResultUrl
Source: CVE Program / CVE List V5
Vulnerability Description
n8n before 1.123.64, 2.29.8, and 2.30.1 contains a stored DOM cross-site scripting vulnerability in the Resource Locator component, which passes the workflow-persisted cachedResultUrl parameter to window.open() without scheme validation. An attacker with workflow creation/editing privileges can craft a workflow with a malicious (e.g., javascript:) scheme in cachedResultUrl; when a victim opens the crafted workflow and interacts with external links, the payload executes in the victim's browser.

Vulnerability Title
n8n 跨站脚本漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
n8n是n8n公司开源的一个可扩展的工作流自动化工具。 n8n 1.123.64之前版本、2.29.8之前版本和2.30.1之前版本存在跨站脚本漏洞，该漏洞源于Resource Locator组件将工作流中持久化的cachedResultUrl参数传递给window.open()时未进行模式验证，可能导致具有工作流创建/编辑权限的攻击者构造带有恶意模式（如javascript:)的cachedResultUrl，当受害者打开特制工作流并与外部链接交互时，有效载荷在受害者浏览器中执行。
