Description:

While making an account in demo.avideo.com I found a parameter "?success=" which did not sanitize any symbol character properly which leads to XSS attack.

Impact:

Since there's an Admin account on demo.avideo.com attacker can use this attack to Takeover the admin's account

Step to Reproduce:

1. Click the link below

https://demo.avideo.com/user?success="><img src=x onerror=alert(document.cookie)>

2. Then XSS will be executed
