CVE-2023-51XX2

The Code Review Patch challenges are designed to enhance your ability to identify security vulnerabilities by reviewing code changes. In this particular challenge, you are presented with the core/auth/auth.go file, which handles JWT authentication in the application. Initially, try to locate the security issue by analyzing the code. If you struggle to find the issue or wish to verify your findings, you can refer to the provided patch file, cve-2023-51xx2.diff.

The patch makes several critical changes to the initialization of the JWT secret key. Previously, the code fetched a secret from the datastore with a default fallback to a weak, hardcoded value. The patch improves this by generating a unique secret using uuid.NewString() if no secret is found, significantly enhancing the security of token generation. This exercise helps you understand the impact of secure secret management and the importance of avoiding hardcoded values in security-sensitive contexts.
