The Code Review Patch challenges are designed to enhance your ability to identify and understand vulnerabilities in code by providing both the vulnerable code and its corresponding patch. Initially, you should try to spot the issue without looking at the patch, which helps in sharpening your code review skills and understanding the context of the vulnerability. If you find it difficult to locate the issue or wish to validate your findings, you can then refer to the patch for clarification.

These challenges involve analyzing real-world code from projects like openmeetings-db, where you will inspect Java files and their patches. For instance, you might examine the `InvitationDao` class, which manages database operations for invitation entities, and the `Invitation` entity class, which defines the structure and behavior of invitation records. By comparing the original code with the patched version, you will gain insights into how vulnerabilities are identified and resolved in professional software development.
