CVE-2026-6470

CVE-2026-6470 · PostgreSQL fails to check type USAGE privilege

This page contains facts from public vulnerability sources. Check the original advisory before updating.

Missing authorization in PostgreSQL DDL commands allows an object creator to achieve denial of service against ALTER and DROP of the type, via creating a dependency on the type. Many DDL operations did check the privilege, but assigning a range subtype and referencing the type from an SQL expression did not. Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.
