CVE-2026-116313
PostgreSQL "vacuumdb --missing-stats-only" lets a database owner execute code as the vacuumdb user
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.
