  "details": "Improper protection of alternate path in PostgreSQL security-restricted operations allows an object creator to execute arbitrary SQL as the operation's caller, via a domain, enum, or range type created in pg_temp.  The victim session must later run a query containing an unqualified type name, e.g. \"SELECT '1'::bigint\"; autovacuum and other common security-restricted operation users do not do so, so they are unaffected.  Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.",
