Fixing OWASP API2:2023 — Broken Authentication in Symfony 7
Security is not an afterthought, it’s fundamental
Introduction
If you’re diving into web development with PHP, Symfony 7 is an amazing framework to build robust APIs. But here’s the catch: security isn’t optional.
The OWASP API Security Top 10 highlights the most critical risks to APIs, and today, we’ll tackle API2:2023 — Broken Authentication. This vulnerability happens when an API fails to properly verify who’s accessing it, leaving the door wide open for attackers.
In this step-by-step guide, we’ll:
- Build a simple Symfony 7 API endpoint that is vulnerable to Broken Authentication.
- Understand why it’s vulnerable according to OWASP API2:2023.
- Implement a fix using Symfony’s built-in security features.
By the end, you’ll have a working API, understand the security flaw, and know how to patch it.
