Summary

Glad this kick-started my interest in penetration testing! Pretty interesting bug somewhere deep in the source code.

How it was found

Hello Brave, https://hackerone.com/smelt and I found a glitch for Brave on Windows.

Summary:

If you run the javascript code confirm(), Brave will crash. This is major for a glitch, because people may be visiting websites that have confirm messages and Brave will suddenly and unexpectedly crash for them.

Products affected:

Doesn't effect Mobile Tested and crashed Windows Brave browser

Steps To Reproduce:

  1. Open Brave
  2. Run the JS code confirm() somehow (Ex. go to my website I made that runs it: pentesting.x10host.com)
  3. Brave will crash

If you have questions or comments please reply here.

Thanks, kicker and smelt
