CVE-2026-6470
Last modified
CVE-2026-6470 is a medium-severity vulnerability rated 4.3/10 on the CVSS scale. 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. EPSS estimates a 0.19% chance of exploitation in the next 30 days.
