The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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)

Note that Nessus relies on the presence of the package as reported by the vendor.
