Description
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.
