CVE-2020-14349
The PostgreSQL search_path setting determines schemas searched for tables, functions, operators, etc. The CVE-2018-1058 fix caused most PostgreSQL-provided client applications to sanitize search_path , but logical replication continued to leave search_path unchanged. Users of a replication publisher or subscriber database can create objects in the public schema and harness them to execute arbitrary SQL functions under the identity running replication, often a superuser. Installations having adopted a documented secure schema usage pattern are not vulnerable. The PostgreSQL project thanks Noah Misch for reporting this problem.
