OWASP's list of the most critical API security risks (2023 edition), led by broken object level authorization, broken authentication and unrestricted resource consumption, with attack scenarios and prevention advice for each. Anyone building a backend should read it once and use it as a checklist, because these flaws are common and often easy to miss in code review. It describes risks rather than implementation steps, so pair it with the OWASP Cheat Sheet Series.
