The newly released Claude 3.7 Sonnet model was commissioned to generate a classic CRUD application, and the output was examined for security vulnerabilities using Snyk's IDE extension. While no known vulnerabilities were detected in the generated code, cybersecurity professionals identified a few issues, including an email validation vulnerability that could be exploited by attackers due to its use of greedy quantifiers, which can cause Denial of Service issues. Despite this, the model performs better than earlier versions of Anthropic's Sonnet series and outperforms some competitors, such as GitHub Copilot and ChatGPT 4o, in terms of security vulnerabilities. The experiment highlights the importance of using tools like Snyk to help developers write secure code from the start.
