Assume that two vulnerabilities, $"x"$ and $"$Y$",$ for example, are scored equally on the Attack Vector $($AV$),$ Attack Complexity $($AC$),$ and Privileges Required $($PR$)$ metrics in the Base Metric group.

In terms of User Interaction $($UI$)$ however:

Assume that, vulnerability $"x"$ requires some sort of user action before the vulnerability can be exploited and vulnerability $"$Y$"$ can be exploited without any user interaction. That is$,$ an attacker can exploit vulnerability $"Y"$ at will and does not need the user to participate to make the attack successful.

Given the above assumptions, which vulnerability will receive a greater CVSS v$.3\mathrm{.}1$ Base Score $($i$.$e$.$ which one is worse?$)$
