That’s strange. I’ve never came across such issue prior to this. Anyway, I think you would be able to redirect the specific URL pattern to home page with proper URL or 404 page.

Please see below.
URL Redirection

PS: What about custom redirection specific codes in function.php?

AFAIK this can happen due to 2 reasons.

1. Modified .htaccess file with custom URL redirections
2. Custom endpoints with redirection hooked to WordPress via functions.php

Check those two possibilities.
(Also check whether there are any plugins activated related to URL redirection)
