Doc Text:
A flaw was found in PostgreSQL. Missing authorization checks in logical replication allow a compromised publisher to execute arbitrary code as the operating system user running the database service. An attacker controlling a publishing database can exploit this vulnerability by designating an internal system catalog table as a replication target for a superuser-owned subscription.

Description OSIDB Bzimport 2026-11-12 14:33:01 UTC
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.
