This issue can be reached over the network, attack complexity is high, an attacker needs no privileges on the target. A user must be tricked into taking some action. The scope is changed, meaning a successful attack can affect components beyond the vulnerable one. Rated impact: confidentiality high, integrity low, availability high.

CVSS metrics in full

• User interaction: Required — someone has to click, open or visit something.
• Scope: Changed — a successful attack reaches components beyond the vulnerable one.
• Confidentiality impact: High — total loss, or loss the attacker controls.
• Integrity impact: Low — limited, and the attacker does not choose what is affected.
• Availability impact: High — total loss, or loss the attacker controls.
