Be careful when copying code: why AI-generated code carries risks
The rapid development of artificial intelligence has revolutionised many industries, particularly software development. AI tools capable of generating blocks of code or entire functions are hailed by developers worldwide as efficiency boosters. Yet this apparent convenience conceals significant risks that companies and developers often underestimate. Experts warn against adopting AI-generated code uncritically, as this can cause serious security vulnerabilities and unexpected problems.
Lack of context and security awareness
The main problem with AI-generated code is its fundamental lack of contextual understanding. An AI is trained on vast amounts of data from public repositories, forums and tutorials. It learns patterns and writes code that appears statistically "correct". What it does not understand, however, is the specific requirements of a project:
- Security requirements: an AI cannot distinguish between secure and insecure coding practices unless it has been explicitly trained to do so. It knows neither a company's individual security policies nor the specific threats an application faces. This can unintentionally introduce vulnerabilities such as SQL injection, cross-site scripting (XSS) or insecure data processing.
- System architecture: an AI model does not understand the overall architecture of an application. It does not know how a section of code needs to be integrated into the existing system or what dependencies and side effects it might have. The result can be code that is difficult to debug and maintain.
- Unknown origins: AI models can generate outdated or suboptimal code drawn from older, insecure sources. Without human review, there is a risk that apparently functional code already contains known security issues.
High costs of remedial work
The apparent time savings from using AI-generated code can quickly have the opposite effect. Identifying and fixing security vulnerabilities and integration problems afterwards is often more time-consuming and expensive than writing the code carefully and according to best practices from the outset.
A developer who blindly copies code from an AI without understanding and checking it is acting with immense irresponsibility. We repeatedly see AI-generated code that ends up in production systems lead to unnecessary risks that could have been avoided. AI should serve as a supporting tool, not as a replacement for expertise and critical thinking.
Companies are therefore urged to establish clear guidelines for using AI tools in software development. A rigorous code review process that also critically examines AI-generated sections is essential to ensure the integrity and security of applications. This is the only way to benefit from AI's productivity without compromising the fundamental principles of software development and cybersecurity.
