"The vulnerability, tracked as CVE-2025-68613, carries a CVSS score of 9.9 out of a maximum of 10.0. The package has about 57,000 weekly downloads, according to statistics on npm. "Under certain conditions, expressions supplied by authenticated users during workflow configuration may be evaluated in an execution context that is not sufficiently isolated from the underlying runtime," the maintainers of the npm package said."
""An authenticated attacker could abuse this behavior to execute arbitrary code with the privileges of the n8n process. Successful exploitation may lead to full compromise of the affected instance, including unauthorized access to sensitive data, modification of workflows, and execution of system-level operations." The issue, which affects all versions including and higher than 0.211.0 and below 1.120.4, has been patched in 1.120.4, 1.121.1, and 1.122.0."
The n8n workflow automation platform contains a critical vulnerability (CVE-2025-68613) that can enable arbitrary code execution when exploited. The flaw has a CVSS score of 9.9. Authenticated user-supplied expressions during workflow configuration can be evaluated in an execution context insufficiently isolated from the runtime, allowing escalation to arbitrary code execution with n8n process privileges. Successful exploitation may lead to full instance compromise, data exposure, workflow modification, and system-level operations. Affected versions include all versions >=0.211.0 and <1.120.4; patches are available in 1.120.4, 1.121.1, and 1.122.0. Mitigation includes immediate patching, restricting workflow editing to trusted users, and hardening deployment with limited OS privileges and network access.
