Description
Missing authorization in PostgreSQL logical replication allows a compromised publisher to execute arbitrary code as the operating system user running the superuser-owned subscription, via naming a system catalog as a replication target. Only subscriptions owned by a superuser are vulnerable. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.
