Description

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.

Affected products

• Red Hat JBoss EAP: 7.0.0
• Wildfly: from 11.0.0 through 16.0.0
