Title
PostgreSQL expression deparse allows SQL injection via EXTRACT argument
Summary
SQL injection in PostgreSQL EXTRACT() deparse allows an object owner to execute arbitrary SQL as a superuser via a hostile object definition. Attacks affect expression deparse consumers broadly, including pg_dump, psql commands like \sf, and any similar usage in non-core tools. Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.
