Hi, how are you replicating this issue? Have you disabled all plugins as well as activated one of the default themes such as TwentyNineteen or similar and you were able to replicate the issue still then?

Hi @ram181 and welcome to Core Trac.
This is the place where we confirm and follow-up on bugs in WordPress core, we don't provide user support here. A much better place to ask would be ​https://wordpress.org/support/forum/how-to-and-troubleshooting/

Having said that, what you're describing here looks as if you've been hacked. Start by reading ​https://wordpress.org/support/article/faq-my-site-was-hacked/

Thanks for the commenting on my ticket, but I face this problem on 15 websites that's a reason I thought that it's related to Wordpress bug.
