Echo: pglogical: security update to 2.4.8

critical Tenable Self-Hosted Container Security Plugin ID 459801

Description

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

 - When applying replicated changes for a row that is missing one or more columns, pglogical evaluates the
 affected table's default expressions on the subscriber. Because the apply worker runs at a privilege level
 equivalent to a PostgreSQL superuser in default installations, any function invoked by such a default
 expression also runs at that privilege. A party acting as the publisher can use this path to cause
 functions to be executed on the subscriber as superuser, escalating from a role permitted to use pglogical
 to full superuser. This is a second, independent path to the same superuser escalation tracked under
 CVE-2026-50736 (the pglogical queue issue). 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-2026-50737)

Solution

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