Re: [Full-disclosure] yahoomail dom based xss vulnerability

[ㅤ ㅤRockey <skg102@xxxxxxxxx>]

Thanks for your information pratul

I do know about DOM and XSS, I wasn't able to reproduce this bug on my end
that's why i requested you to post video on that.

I do agree with vipul that this is not working, and I checked this bug twice
already so i am quite sure about it that this flaw isn't working on
yahoomail. If in case this works then please come up with a POC video :)

Looking forward for your response :)

Cheers,
Rockey
