High 7.8
In plain English
A high-severity security flaw in Windows 10 Version 1903 for 32-bit Systems from Microsoft. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 1.0% (higher than 61% of all known vulnerabilities).
Official description
An elevation of privilege vulnerability exists when Windows improperly handles calls to Clipboard Service. An attacker who successfully exploited this vulnerability could run arbitrary code in the security context of the local system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and take control over an affected system. The update addresses the vulnerability by correcting how Windows handles calls to Clipboard Service.
