Acknowledgement From Hubspot

This website has web-based advertising online tools which minimizes our work to such an extent. They have likewise an Email Signature maker which is vulnerable to Cross-Site Scripting (XSS). My companion proposed to me HubSpot Academy for finding out about Email Marketing tutorials. I have investigated their site and established that this Email Signature is vulnerable to Cross-Site Scripting (XSS) vulnerability. In spite of the fact that they additionally have a Responsible Disclosure program on BugCrowd however, I never noticed.

Below I'll show you I replicate Cross-Site Scripting (XSS) in HubSpot

Go to HubSpot Email Signature maker.

In the Email Signature required data frame, fill these fields with XSS payloads. This page is reacting invigoratingly to the ideal frame.
