BIT-wordpress-multisite-2020-4050: Low severity WordPress WordPress vulnerability
In affected versions of WordPress, misuse of the set-screen-option filter's return value allows arbitrary user meta fields to be saved. It does require an admin to install a plugin that would misuse the filter. Once installed, it can be leveraged by low privileged users.
