Description

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.
