CVE-2026-50736 Detail
Received
This CVE record has recently been published to the CVE List and has been included within the NVD dataset. DescriptionThe pglogical queue mechanism, used to convey out-of-band commands such as replicated DDL from a publisher to a subscriber, executes message payloads on the subscriber at the privilege level of the apply worker, which is equivalent to a PostgreSQL superuser in default installations. A party acting as the publisher can send crafted queue messages that cause arbitrary SQL to be executed on the subscriber as superuser, escalating from a role permitted to use pglogical to full superuser and breaking the isolation between tenants in shared deployments. To exploit the issue an attacker must be able to direct a subscription at an endpoint they control. In default installations this requires privileges normally reserved for a superuser, so the issue is most relevant to managed deployments where the ability to create subscriptions has been delegated to non-superuser roles.
