Website compromised? Spam 'page' links created, need help to remove

My Wordpress website has reported back a large number of 'pages' - according to Google search console - that were not created by me. Somehow my website has been compromised and I don't know how, or where these pages / URL's have been created. I cannot see these pages within my Wordpress, only in Google Search Console (see attached screenshot - none of these URL's were created be me). I am looking for someone to find and remove what has happened here.
