Name of the Vulnerable Software and Affected Versions PostgreSQL versions prior to 18.5 PostgreSQL versions prior to 17.11 PostgreSQL versions prior to 16.15 PostgreSQL versions prior to 15.19 PostgreSQL versions prior to 14.24

Description Missing authorization in Data Definition Language (DDL) commands allows an object creator to cause a denial of service against the ALTER and DROP operations of a type by creating a dependency on that type. While many DDL operations verify privileges, assigning a range subtype and referencing the type from an SQL expression does not.

Recommendations Update to version 18.5 or later. Update to version 17.11 or later. Update to version 16.15 or later. Update to version 15.19 or later. Update to version 14.24 or later.
