ElytronManagedThread Vulnerability: Incorrect Security Identity Assignment

CVE-2019-3894 · HIGH Severity

CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

It was discovered that the ElytronManagedThread in Wildfly's Elytron subsystem in versions from 11 to 16 stores a SecurityIdentity to run the thread as. These threads do not necessarily terminate if the keep alive time has not expired. This could allow a shared thread to use the wrong security identity when executing.
