In this Code Review Patch challenge, participants are given a piece of vulnerable code along with a patch that fixes the issue. The primary objective is to scrutinize the code and identify the vulnerability without referring to the patch initially. This approach aims to enhance your code review skills by making you depend on your analytical abilities first before using the patch for validation.

For this specific challenge, focus on identifying the line where the value is retrieved rather than where it is used. By understanding the context in which the value retrieval happens, you can better comprehend the nature of the issue and how the patch resolves it. This method not only aids in recognizing common coding flaws but also provides insights into secure coding practices.
