WordPress Core is vulnerable to open redirect in versions up to 6.0.3. This is due to insufficient validation of the 'Referer' header and _wp_http_referer request parameter when a user accesses a link with an expired or invalid nonce.

This would make it possible for an attacker to redirect a victim to a potentially malicious site, granted they could trick the victim into performing an action such as clicking on a link.

Not sure which version you run? Run a passive check — it reads public files only.
