CVE-2021-32028
Using an INSERT ... ON CONFLICT ... DO UPDATE command on a purpose-crafted table, an attacker can read arbitrary bytes of server memory. In the default configuration, any authenticated database user can create prerequisite objects and complete this attack at will. A user lacking the CREATE and TEMPORARY privileges on all databases and the CREATE privilege on all schemas cannot use this attack at will.
The PostgreSQL project thanks Andres Freund for reporting this problem.
