CVE-2026-6472

MEDIUM

PostgreSQL CREATE TYPE does not check multirange schema CREATE privilege

Title source: cna

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.
