CVE-2020-4048
In affected versions of WordPress, due to an issue in wp_validate_redirect() and URL sanitization, an arbitrary external link can be crafted leading to unintended/open redirect when clicked.
Does this matter?
Lower severity and a low EPSS score (1.98%). Track it; it rarely justifies an emergency change on its own.
