Echo: pglogical: security update to 2.4.8
medium Tenable Cloud Security Plugin ID 459098
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- pglogical's apply worker does not sufficiently validate the length of certain fields in incoming
replication protocol messages before copying them, resulting in an out-of-bounds read. A party acting as
the publisher for a subscription, for example a non-PostgreSQL endpoint that speaks the pglogical
replication protocol, can return crafted messages that cause the subscriber's apply worker to read beyond
the bounds of an allocated buffer, disclosing adjacent process memory or crashing the worker. 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-2026-50735)
Solution
Update the pglogical library and its related packages to version 2.4.8 or later.See Also
