Description

The vulnerability allows a remote authenticated user to execute arbitrary code.

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.


Remediation

Install update from vendor's website.
