{"id":"RLSA-2026:67280","summary":"Important: postgresql18 security update","details":"PostgreSQL is an advanced Object-Relational database management system (DBMS). The base postgresql package contains the client programs that you'll need to access a PostgreSQL DBMS server, as well as HTML documentation for the whole system.  These client programs can be located on the same machine as the PostgreSQL server, or on a remote machine that accesses a PostgreSQL server over a network connection.  The PostgreSQL server can be found in the postgresql-server sub-package.\n\nSecurity Fix(es):\n\n* postgresql: PostgreSQL: SQL injection in pg_createsubscriber allows arbitrary SQL execution as
