Description Srikanth Balasubramanian 2026-08-31 11:32:24 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

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 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.
