Type confusion in PostgreSQL materialized set-returning functions allows a database user to execute arbitrary code as the operating system user running the database, via returning rows having different dynamic RECORD return types. json_populate_recordset() is one affected function. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.
