The AI reviewer found a real bug. Its suggested fix would have broken my app.
An experiment with an AI code reviewer noted both its strengths and weaknesses in identifying vulnerabilities within the code. The reviewer flagged a serious CSV injection vulnerability only on a strict setting but suggested a fix that would have adversely affected functionality. The author illustrates the complexities of trusting AI suggestions in software development, showing that while AI can identify potential issues, its understanding of specific code context remains limited. This presents a cautionary point for developers who might rely on such tools exclusively without human oversight.
