Won the 1st price at #hack010 @rotterdam (lnkd.in/etkxKTRM) together with @bug_dutch! A yearly event where Rotterdam invites ethical hackers and students to hack them. We ended up with a CVSS 9.2 critical bug in a production system! What is @AmsterdamNL waiting for?

I'm the proud owner of CVE-2024-10000. The bug itself is nothing special, just a good old stored XSS, but I do like the CVE number😁
