If you're a developer looking to better understand security vulnerabilities, this is one of the best books out there on the topic. While this book specifically focuses on Command Injection vulnerabilities in Node, the content contained within is broadly applicable to any developers writing software. It's an A++ book and absolutely worth the time to read and analyze. Liran is a top-tier security researcher and developer who's an icon in the security space. Seriously, look him up on Google, he's amazing.

On point content, short book just for my liking. I like the interesting facts in the middle and code examples are good. I like the approach of Risk -> Solution -> Implementation

This was targeted at a perfect level for me, as someone who had exposure to these topics, had done some fiddling with helmet previously in node, but this was a great succinct guide to quickly and effectively teach "what" and "why".
