Echo: pglogical: security update to 2.4.8

high Tenable Self-Hosted Container Security Plugin ID 459401

Description

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

 - A use-after-free condition exists in pglogical's worker signaling code, where a worker structure can be
 dereferenced after the underlying slot has been freed or recycled during normal worker lifecycle events.
 The condition is reachable during normal replication operation, including by a low-privileged user able to
 influence worker start, stop, and restart timing through permitted pglogical operations. In the typical
 case the condition crashes replication workers, causing an availability impact. In the worst case a use-
 after-free in a PostgreSQL backend can be leveraged as a remote code execution primitive at the privilege
 of that backend. (CVE-2026-50738)

Solution

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