CVE-2026-6472
MEDIUM5.4EPSS 0.03%PostgreSQL CREATE TYPE does not check multirange schema CREATE privilege
Published: 5/14/2026Modified: 5/25/2026
Description
Missing authorization in PostgreSQL CREATE TYPE allows an object creator to hijack other queries that use search_path to find user-defined types, including extension-defined types. That is to say, the victim will execute arbitrary SQL functions of the attacker's choice. Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected.
