Secure Code Review Series

Hey 👋

I’m starting a new series based on my experiences and findings as a secure code reviewer.

As bug bounty hunters, we usually see vulnerabilities through HTTP requests, responses, payloads, and how the application behaves externally.

But during secure code review, vulnerabilities look completely different. Instead of observing behavior from the outside, we analyze patterns directly in the source code.

Things like: • User input concatenated into queries • Unsafe string formatting

These patterns often reveal vulnerabilities even before the application is run.

In this series, I’ll walk through how common security issues appear during backend source code review and what security reviewers usually look for while analyzing code.
