NVD Description

Note: Versions mentioned in the description apply only to the upstream postgresql18 package and not the postgresql18 package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

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.
