Hello friends, welcome back!
Today, I’ll be sharing how I discovered a Clickjacking vulnerability and successfully chained it with an open redirect to earn a $140 bounty 💰. It’s a great example of how chaining simple bugs can lead to real impact. Whether you’re new to bug hunting or experienced hunter you’re more than welcome here. Let’s dive in! 🔍
Clickjacking is something many of us in the security space have come across before, but just to keep things clear, let’s quickly revisit what it actually is.
Clickjacking is a trick where users are made to click on something without realizing it, usually by showing a real page inside a hidden or fake frame, so the user thinks they’re clicking one thing, but they’re actually clicking something else.
“Let’s see how I chained Clickjacking with an Open Redirect.”
1 -> Let’s consider the target as redacted.com. I found the vulnerability on the “Login” page, As I was Doing Login process I thought, “Why not test for Clickjacking real quick?” It’s simple, but you never know what might turn up.
2 -> I visited to clickjacker.io to test the url and confirming the Clickjacking issue, I realized it might not be enough on its own to qualify for a bounty. So, I thought to chain it with something more impactful.

3 -> I decided to chain it with Open redirect which can be classified as a low or medium severity.. I wrote a HTML code in a notepad file. Which allowed me to combine both vulnerabilities and demonstrate how they could be exploited together.
