PostgreSQL CREATE TYPE does not check multirange schema CREATE privilege_CVE-2026-6472

{
    "lastseen": "",
    "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.",
