"The version of PostgreSQL installed on the remote host is 10 prior to 10.22, 11 prior to 11.17, 12 prior to 12.12, 13
prior to 13.8, or 14 prior to 14.5. As such, it is potentially affected by a vulnerability :
  - A vulnerability exists in postgresql. On this security issue an attack requires permission to create non-temporary 
objects in at least one schema, ability to lure or wait for an administrator to create or update an affected extension 
in that schema, and ability to lure or wait for a victim to use the object targeted in CREATE OR REPLACE or CREATE IF 
NOT EXISTS. Given all three prerequisites, the attacker can run arbitrary code as the victim role, which may be a 
superuser. Known-affected extensions include both PostgreSQL-bundled and non-bundled extensions. PostgreSQL blocks this 
attack in the core server, so there's no need to modify individual extensions. (CVE-2022-2625)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
