Description

A security issue was found in PostgreSQL before version 13.3. 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.
