Description OSIDB Bzimport 2026-05-14 14:01:33 UTC 
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.
