Echo: pglogical: security update to 2.4.8

critical Tenable Cloud Security Plugin ID 463926

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - The 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. (CVE-2026-50736)

Solution

Update the pglogical library and its related packages to version 2.4.8 or later.
