Description

Siren Federate before 6.8.14-10.3.9, 6.9.x through 7.6.x before 7.6.2-20.2, 7.7.x through 7.9.x before 7.9.3-21.6, 7.10.x before 7.10.2-22.2, and 7.11.x before 7.11.2-23.0 can leak user information across thread contexts. This occurs in opportunistic circumstances when there is concurrent query execution by a low-privilege user and a high-privilege user. The former query might run with the latter query's privileges.
