Recently, a serious security vulnerability identified as CVE-2025-68613 was discovered in the open-source workflow automation platform, n8n. This vulnerability can allow attackers to execute arbitrary code remotely, posing a significant threat to server security.
The vulnerability affects n8n versions from 0.211.0 up to 1.122.0. It arises during workflow expression evaluation, where expressions inputted by authenticated users can execute in a less isolated runtime context. This allows an attacker to run code with the privileges of the n8n process.
Successful exploitation of this vulnerability could allow unauthorized access to sensitive data, modification of workflows, and unauthorized execution of system-level operations. This raises significant concerns for system administrators and hosting providers who manage critical infrastructures.
For server admins and hosting providers, ensuring server security is paramount. The emergence of this vulnerability presents not only a risk to individual systems but to entire networks. A compromised server can result in data theft, reputation damage, and financial loss.
To mitigate the risk associated with this vulnerability, it is critical to take immediate actions:
