An issue was discovered in EnterpriseDB Postgres Advanced Server (EPAS) before 11.21.32, 12.x before 12.16.20, 13.x before 13.12.16, 14.x before 14.9.0, and 15.x before 15.4.0. It contains the function _dbms_aq_move_to_exception_queue that may be used to elevate a users privileges to superuser. This function accepts the OID of a table, and then accesses that table as the superuser by using SELECT and DML commands.
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
