Untrusted search path in PostgreSQL vacuumdb allows a database owner to execute arbitrary SQL as the database user running vacuumdb, via shadowing operators used in the --missing-stats-only catalog query. The pg_upgrade documentation recommends an affected vacuumdb invocation. Within major version 18, minor versions before PostgreSQL 18.7 are affected. Versions before PostgreSQL 18 are unaffected.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
