Automation, Integration and Security: What the n8n Vulnerability Reveals About Modern Digital Infrastructure

The digital transformation of the past decades has brought a profound shift in how systems are built and operated. Applications no longer exist in isolation; instead, they constantly connect with other services, APIs, databases, and cloud platforms. In this environment, automation tools have taken on a central role in modern software engineering. They act as bridges between systems, allowing different services to communicate automatically and efficiently. Among these tools, n8n quickly gained recognition within the community of developers, DevOps engineers, and solution architects. Its proposal is simple yet extremely powerful: enabling the creation of automated workflows that connect different applications and execute complex tasks without manual intervention. Recently, however, a piece of news captured the attention of the technology community. Security researchers identified critical vulnerabilities in n8n that could expose thousands of servers to potential cyberattacks. The discove
