Does this matter?

Lower severity and a low EPSS score (0.98%). Track it; it rarely justifies an emergency change on its own.

Description

A malicious actor with non-administrative user access to the vCenter Server vSphere Client (HTML5) or vCenter Server vSphere Web Client (FLEX/Flash) may exploit this issue to create a denial-of-service condition on the vCenter Server host.
