During #x3ctf, I discovered an unintended solution that turned out to be a pretty cool generic technique. It allows you to detect the result of a selector during CSS Injection, bypassing any CSP restricting external requests!

Here is (finally) the writeup and conclusion of the challenge:

Maybe not the best write-up, but I have to allow myself to actually post, rather than refactor, posts. I hope someone finds it useful. And thanks everyone that participated. Special shoutout to @terjanq.me
One thing that I was missing when using the tool was to get the entire output rather than body. Another thing was being able to copy to clipboard generated input and output. These would be useful!

The latest version should be quite straightforward. If you like magic, then I recommend checking out the previous version 😄 terjanq.me/solutions/jo...
It includes more trickier races 😅
Managed to greatly improve:
* performance
* accurracy
* cross-platform support (should now work on both Chrome & Firefox)
Check out the updated version! 😃

Helps a lot with longer threads!
Imagine opening a Discord message and suddenly your computer is hacked.
We discovered a bug that made this possible and earned a $5,000 bounty for it.
Here's the story and a beginner-friendly deep dive into V8 exploit development.

11 chars with bsky.app/profile/terj...
Got sniped into the challenge and ended up doing some cool XSS research :D
11 char XSS with mind-boggling race-conditions.
TL;DR the final payload is location=x (10 chars) and the longest is top.Z.x=x.d (11 char)
It's shorter than location=name !!

Slow race condition but 11 chars! terjanq.me/solutions/jo... Let me know if that works for you. With that, time to stop 😅
12 with open() terjanq.me/solutions/jo...
Without popups enabled, you have to click on any iframe when the bg becomes pink.
I disregarded open() because it needs interaction so I didn't look too much into it. The culprit for buildup. I'm not sure how to make it 11 as top.r.d+="1" is already 12. it should be possible with 12 via top.x.x=top and then open(r.x.d) which is 11
Can do it also in 12, but I agree that it's cheating with run.

13* haha :D
15 terjanq.me/solutions/jo...
Can be most likely improved but didn't yet figure out how to properly race condition with shorter payloads like top.x.x+="" 😶

Extended the starter with shy writers! 😀 If you're not on the list but write about web security, then feel free to reply with the article you're most proud of, and I will add you to the pack!

Getting this for 2 years already :( new number most of the time. When I just moved to Switzerland, I found a paper slip from post to receive some important lettters. When I go to the post office it was all scam. The most targeted scam I ever received 😅
I started a Web Security Writers starter pack. Had to add 7 accounts so settled on a couple of obvious names but the idea I have for the starter is different. Please share your BEST writeup / article in the reply and I will add you to the pack! Let's shake the platform a bit with amazing research! 🕸️
Feel free to drop a banger here regardless! :D
Starter pack seems to be glitched on web, the URL is: bsky.app/starter-pack...
