CVE-2026-6472 Details
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.
A vulnerability exists in PostgreSQL versions prior to 18.4, 17.10, 16.14, 15.18, and 14.23, where the CREATE TYPE command lacks proper authorization checks. This flaw enables an object creator to intercept and manipulate other queries that rely on the search_path to locate user-defined types, including those defined by extensions. As a result, the targeted queries may execute arbitrary SQL functions specified by the attacker.
Users can upgrade to PostgreSQL versions 18.4, 17.10, 16.14, 15.18, or 14.23 to address this vulnerability.
