DISPUTED In PostgreSQL 9.3 through 11.2, the “COPY TO/FROM PROGRAM” function allows superusers and users in the ‘pg_execute_server_program’ group to execute arbitrary code in the context of the database’s operating system user. This functionality is enabled by default and can be abused to run arbitrary operating system commands on Windows, Linux, and macOS. NOTE: Third parties claim/state this is not an issue because PostgreSQL functionality for ‘COPY TO/FROM PROGRAM’ is acting as intended. References state that in PostgreSQL, a superuser can execute commands as the server user without using the ‘COPY FROM PROGRAM’.

There’s some interesting debate around the couching of this as a vuln in PostgreSQL, itself, since the COPY TO/FROM PROGRAM is ostensibly documented to allow program execution. Certainly a good reminder to, in general, limit privs where possible (in this case, don’t grant ‘pg_execute_server_program’ to users who don’t require it).
