This could allow a shared thread to use the wrong security identity when executing.

HIGH 8.8EPSS 1.48%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (1.48%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

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.
