Funny thing is you're using a browser that shows the origin in the alert box regardless of message, so alert(1) is fine in those browsers. Though you do show the edge case where there is no origin (eg it's blank) the alert box title is different, so it's worth keeping that edge case in mind.

The browser may show the origin in the alert but I think you're missing the point. It's not a bug. Using alert(1) would render a false positive and it would be better to use something other than alert(1) that shows an actual xss on the origin.

The reason we use alert is because of old browsers that didn't have such nice consoles. It was the easiest way to see something on screen. In fact I remember an old Microsoft site where I got a debug alert when I pressed some combination of buttons (by chance).

Huh, never considered the bug bounty angle. From my experience with clients, issues in the components of a client's application were still very valid, and would often prompt further discussion and remediation across org boundaries, which I see as the ideal outcome. Good practice for XSS checks nonetheless, great video!

saw a few german youtuber doing this for legal reasons. Otherwise competitors will assume you are breaking a law if some products are highlighted in the videos, even if there is no sponsorship. They will ask for money and for you to stop doing this in the feature (with some legal document ). In return those youtuber then have to explain that there is no sponsorship and might even need the assistance of a lawyer. If it was sponsored he probably has to pay money to the competitor. So they just place a advertisement note on every single video to just not having to deal with that kind of bullshit.

Chrome and Firefox both always display the origin domain in the alert, shown in the video for example at 3:41. I don't see the point of writing such a unnecessarily long payload, the video title seems a bit much clickbait, otherwise good explanation tho. alert(1) is still fine. btw: Opera and Vivaldi do it too, I guess all chromium based browsers.

You make your videos really well. Amazing script, you speak clearly and enthusiastically, and you make cool graphics that are easy to understand and look nice in general, etc... The only thing I can complain about is that your IRL background looks kinda scary, like you are about to make an apology video or a documentary. It's not really a complaint but I though you could use the feedback. If you still have the breadboard pc you could make a counter and hang it in the background...or add some shelves or something. Unless you like the empty backdrop in which case ignore what I just said. Keep up the good work!
