CVE-2019-20923
A user authorized to perform database queries may trigger denial of service by issuing specially crafted queries, which throw unhandled Javascript exceptions containing types intended to be scoped to the Javascript engine's internals.
Does this matter?
Lower severity and a low EPSS score (1.27%). Track it; it rarely justifies an emergency change on its own.
Description
