This podcast episode thoroughly examines the security risks associated with the use of top-level `use server` in NextJS applications, emphasizing the critical need for developers to implement proper authentication and code review practices to prevent the accidental exposure of sensitive data. The speaker articulates that while `use server` can enhance functionality by allowing function composition and reuse, it simultaneously poses significant security vulnerabilities if developers do not adopt a disciplined approach to data access and permissions. By establishing best practices and prioritizing security, developers can harness the power of `use server` responsibly.
