I remember reading this when I was the sole Infrastructure Engineer for Reverb.com. I knew we were being attacked and I knew we had issues but I didn't have any idea where to start. This article sparked my interested in Cyber Security and helped me find a bug in the website that allowed me to set the CEO's credit card as a primary card on my account in production. That was an amazing day.
Thanks to the author of the article for inspiring me to dig in the rails codebase and find vulnerable patterns that I could exploit. Thankfully I was able to pivot into a cyber security focused career and I credit this article for starting me down that path.
Rails has a few things going for it that other languages and frameworks don't but it still lets you shoot yourself in the foot if you're not careful. I ended up writing a blog article about preventing XSS in rails as a direct inspiration from the OPs article:

All I had to do was modify a post parameter in flight and the backend would accept it. Turns out this is what is known as an "unscoped find". More info here: https://brakemanscanner.org/docs/warning_types/unscoped_find...
