[內容說明]
n8n是一款開源工作流程自動化工具,透過視覺化拖拉介面串接多種應用程式,無需程式碼即可自動化重複性任務。近期n8n發布多個重大資安漏洞公告。
【CVE-2025-68613,CVSS:9.9】 此為遠端程式碼執行漏洞,在特定條件下,允許經身分驗證的攻擊者以n8n行程的權限執行任意程式碼。
【CVE-2025-68668,CVSS:9.9】 由於n8n使用Pyodide的Python程式碼節點存在沙箱繞過漏洞,經身分驗證且具有建立或修改工作流程權限的攻擊者,以n8n行程相同權限在n8n伺服器上執行任意命令。
【CVE-2026-21877,CVSS:10.0】 此漏洞允許經過身分驗證的攻擊者,可利用n8n服務執行惡意程式碼,導致系統完全被破壞。
【CVE-2026-21858,CVSS:10.0】 此漏洞允許未經身分驗證的攻擊者,可透過執行某些基於表單工作流程,存取底層伺服器的檔案,導致儲存在系統中的敏感資料外洩。

[Content Description]
n8n is an open-source workflow automation tool that connects various applications through a visual drag-and-drop interface, automating repetitive tasks without requiring code. Recently, n8n released several major cybersecurity vulnerability announcements.
【CVE-2025-68613, CVSS: 9.9】 This is a remote code execution vulnerability. Under certain conditions, it allows an authenticated attacker to execute arbitrary code with the privileges of an n8n process.
【CVE-2025-68668, CVSS: 9.9】 Due to a sandbox bypass vulnerability in the Python code node used by n8n in Pyodide, an authenticated attacker with permissions to create or modify workflows can execute arbitrary commands on the n8n server with the same privileges as the n8n process. [CVE-2026-21877, CVSS: 10.0] This vulnerability allows an authenticated attacker to execute malicious code using the n8n service, resulting in complete system compromise.
[CVE-2026-21858, CVSS: 10.0] This vulnerability allows an unauthenticated attacker to access underlying server files by executing certain form-based workflows, leading to the leakage of sensitive data stored in the system.
[Affected Platforms]
n8n versions 0.211.0 to 1.120.4 (excluding 1.120.4) and earlier
n8n version 1.121.0
