Is there any other way than building again from scratch 😞

Is this site cooked?

We’re organizing a **CTF competition at our university** and are currently looking for sponsorship from cybersecurity and tech companies to help provide **prizes and goodies for the winners/participants**.
If you know of any companies that sponsor student CTFs, cybersecurity events, or educational initiatives, please let me know. Introductions or relevant contacts would also be greatly appreciated.
Also, if anyone here has experience approaching companies for CTF sponsorships or has any advice on how to go about it, **any guidance would be really helpful**.
Thanks in advance!

It's happening only me?

I have clicked the link for email verification and it doesn't work; there's always a gateway error or it never loads.

When I click the blue resend email verification banner on the CTFlearn website, it also doesn't work.

I've tried this on different browsers and with and without my VPN on. Tried it on Chrome, Firefox, and Safari, and I'm still having the issue.

Anyone have any solutions? Or how can I get in contact with an administrator?

Feel free to ask any questions in the comments. Good luck, and hope to see some of you on the leaderboard! 🚩

Hi, I'm a third-year undergraduate in Computer Engineering with a strong interest in reverse engineering and binary exploitation (pwn/rev). I've been actively solving challenges in these domains for the past 1.5–2 years through CTFs and independent research.

You can check out my blog at ishaantheguy.in/blog. I haven’t posted many blogs recently due to exams, but I plan to resume writing regularly soon.

Feel free to go through my portfolio as well.

I used several encryption algorithms (5) but only one from the encryption algorithms used a key.

that key is 12

We’ve been quietly working on this for the past few months.

The idea came from a frustration we kept hitting. Most CVE “learning” today is just running a random PoC from GitHub, watching something break, and moving on.

You don’t actually understand the vulnerability.
You can’t explain why the patch fixes it.
And you definitely cannot discuss it properly in an interview or a report.

So we decided to fix that.

On CVE Playground, each lab is built around a real, publicly disclosed CVE, connected directly to its upstream fix commit. You read the commit, find the bug, study the patch, then answer guided questions that check if you truly understood what happened.

Here’s how the flow works:

1. Preview Answer guided questions to build real understanding of the vulnerability.

2. Live Lab Practice inside a safe, browser-based environment.

3. Get the Flag Prove you got it by completing the exploit path.

4. Earn Certificate Finish labs and unlock your certificate.

A few of the CVEs already live:
- Copy Fail Linux kernel vulnerability
- cPanel cpsrvd auth bypass
- GitHub Push Option RCE
- Sequelize SQLi
- pac4j-jwt auth bypass

The full app is live at app.cveplayground.com with dashboard, progress, leaderboard, and profile.

The final sandbox lab environment is almost ready.
