According to the CVSS metrics, successful exploitation of this vulnerability could lead to major loss of confidentiality (C:H), and some loss of integrity (I:L), but no loss of availability (A:N). What does that mean for this vulnerability?
An attacker who successfully exploited this vulnerability could view sensitive information, (Confidentiality), and make some changes to disclosed information (Integrity), but they would not be able to affect Availability.

Why is the severity for this CVE rated as Moderate, but the CVSS score is higher than normal?
Per our severity guidelines, the amount of user interaction or preconditions required to allow this sort of exploitation downgraded the severity, specifically it says, "If a bug requires more than a click, a key press, or several preconditions, the severity will be downgraded". The CVSS scoring system doesn't allow for this type of nuance.
