Open redirect bug issue [ gruntjs.com ]

[dipuhasan]

Hi,

gruntjs.com is vulnerable to open redirect issue, that leads to victim redirecting to unwanted phishing or malicious web pages.

Vulnerable url:
https://gruntjs.com//example.com/

Steps to reproduction :
1 : Add any url after slash / endpoint
2 : While users visit the above url they will get redirected.
https://gruntjs.com//evil.com/

Thanks!

NB: Do you have bug bounty?
