{“lastseen”:”2026-01-28T12:58:00″,”description”:”\\n\\nCybersecurity researchers have disclosed two new security flaws in the n8n workflow automation platform, including a crucial vulnerability that could result in remote code execution.\\n\\nThe weaknesses, discovered by the JFrog Security Research team, are listed below -\\n\\n * **CVE-2026-1470** (CVSS score: 9.9) – An eval injection vulnerability that could allow an authenticated user to bypass the Expression sandbox mechanism and achieve full remote code execution on n8n’s main node by passing specially crafted JavaScript code\\n * **CVE-2026-0863** (CVSS score: 8.5) – An eval injection vulnerability that could allow an authenticated user to bypass n8n’s python-task-executor sandbox restrictions and run arbitrary Python code on the underlying operating system\\n\\n\\n\\nSuccessful exploitation of the flaws could permit an attacker to hijack an entire n8n instance, including under scenarios where it’s operating under \\”internal\\” execution mode. In its documentation, n8n notes that using internal mode in production environments can pose a security risk, urging users to switch to external mode to ensure proper isolation between n8n and task runner processes.\\n\\n\\n\\n\\”As n8n spans an entire organization to automate AI workflows, it holds the keys to core tools, functions, and data from infrastructure, including LLM APIs, sales data, and internal IAM systems, among others,\\” JFrog said in a statement shared with The Hacker News. \\”This results in escapes giving a hacker an effective \\”skeleton key\\” to the entire corporation.\\”\\n\\nTo address the flaws, users are advised to update to the following versions -\\n\\n * **CVE-2026-1470** \\\\- 1.123.17, 2.4.5, or 2.5.1\\n * **CVE-2026-0863** \\\\- 1.123.14, 2.3.5, or 2.4.2\\n\\n\\n\\nThe development comes merely weeks after Cyera Research Labs detailed a maximum-severity security flaw in n8n (CVE-2026-21858 aka Ni8mare) that allows an unauthenticated remote attacker to gain complete control over susceptible instances.\\n\\n\\”These vulnerabilities highlight how difficult it is to safely sandbox dynamic, high\u2011level languages such as JavaScript and Python,\\” researcher Nathan Nehorai said. \\”Even with multiple validation layers, deny lists, and AST\u2011based controls in place, subtle language features and runtime behaviors can be leveraged to bypass security assumptions.\\”\\n\\n\\”In this case, deprecated or rarely used constructs, combined with interpreter changes and exception handling behavior, were enough to break out of otherwise restrictive sandboxes and achieve remote code execution.\\”\\n\\nFound this article interesting?
