## Overview

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.

## Affected

- `postgresql >= 14.0, < 14.24`
- `postgresql >= 15.0, < 15.19`
- `postgresql >= 16.0, < 16.15`
- `postgresql >= 17.0, < 17.11`
- `postgresql >= 18.0, < 18.5`

## Remediation
