In an age characterized by digital transformation, APIs serve as the backbone of modern applications, enabling diverse systems to communicate and share data seamlessly. This widespread API adoption, however, exposes organizations to a considerable attack surface, inviting the attention of cyber adversaries searching for vulnerabilities to exploit.

Over the past several months, we've taken a journey through the new 2023 OWASP API Security Top-10 list. In the previous 12 weekly posts, we've delved into each category, discussed what it is, how it's exploited, why it matters, and suggested effective protections for each. Now, as we conclude this series, it's time to summarize and offer some practical guidance for security practitioners looking to bolster API security in their organizations.

Welcome to the 12th post in our weekly series on the new 2023 OWASP API Security Top-10 list, with a particular focus on security practitioners. In this series we are taking an in-depth look at each category – the details, the impact and what you can do about it. To see previous posts you might have missed, click here. This post will put a spotlight on Injection, which used to be its own category (OWASP API8:2019) but has now been subsumed into OWASP API10:2023 (Unsafe Consumption of APIs).
