P4 Bugs and POC | Part-8

Hi everyone! 👋
I’m Abhijeet Kumawat, a passionate bug bounty hunter and security researcher who loves exploring the fascinating world of vulnerabilities. I believe that even the smallest bugs — like P4 bugs — can be impactful when handled right. Through this blog series, I aim to share my experiences, insights, and hands-on Proof of Concepts (PoCs) to help you uncover these often-overlooked vulnerabilities.

Let’s kick things off with two interesting P4 bugs and learn how to find and exploit them effectively. If you follow these steps and test them on real-world targets, you’re bound to discover some amazing bugs! 😎

HTML Email Injection occurs when an application fails to sanitize user input properly and renders it as HTML in email content. This bug can lead to phishing attacks or the manipulation of official emails.
