Ports are not shown in third-party site redirect warning page.

**Summary:** [Ports are not shown in third-party site redirect warning page] Vulnerable Endpoint :- https://www.semrush.com/redirect?urlhttp://example.com:1337 **Description:** I noticed #311330 this report where you guys fixed a open redirect report by adding a external third-party site redirect warning page . It was a great fix . Although a issue caught in my eye . Urls contains a protocol and Ports . If I add a url with any other ports like 1337 then it's not shown in the external warning page what can be used to take a user to any other place then user expected to go . Browsers Verified In: Chrome and Mozilla Firefox ## Steps To Reproduce: Visit https://www.semrush.com/redirect?url=http://example.com:1337 You will see a warning page only saying about the domain but no warning about the ports like screenshot added below But the source says it will take user to http://example.com:1337 not only example.com <a href="http://example.com:1337" id="js-site-link" class="site_link" data-test-site-link=""> Go to site </a> FIX :- I can suggest possible fix here :- Show the Ports of the inputted url in the Warning page . Thanks ## Impact I noticed in url= parameter many protocols can be used . Like I can use any port and on my android if I visit https://www.semrush.com/redirect?url=http://example.com:1337 and click on Go to site then it will open my virtual environment's.
