The version of postgresql installed on the remote host is prior to 13.14-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2POSTGRESQL13-2024-006 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

"The version of postgresql installed on the remote host is prior to 13.14-1. It is, therefore, affected by a
vulnerability as referenced in the ALAS2POSTGRESQL13-2024-006 advisory.
- Late privilege drop in REFRESH MATERIALIZED VIEW CONCURRENTLY in PostgreSQL allows an object creator to
execute arbitrary SQL functions as the command issuer. The command intends to run SQL functions as the
owner of the materialized view, enabling safe refresh of untrusted materialized views. The victim is a
superuser or member of one of the attacker's roles. The attack requires luring the victim into running
REFRESH MATERIALIZED VIEW CONCURRENTLY on the attacker's materialized view. As part of exploiting this
vulnerability, the attacker creates functions that use CREATE RULE to convert the internally-built
temporary table to a view. Versions before PostgreSQL 15.6, 14.11, 13.14, and 12.18 are affected. The only
known exploit does not work in PostgreSQL 16 and later. For defense in depth, PostgreSQL 16.2 adds the
protections that older branches are using to fix their vulnerability. (CVE-2024-0985)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
