The version of PostgreSQL installed on the remote host is 14 prior to 14.12, 15 prior to 15.7, or 16 prior to 16.3. As such, it is potentially affected by a vulnerability :
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 14 prior to 14.12, 15 prior to 15.7, or 16 prior to 16.3. As
such, it is potentially affected by a vulnerability :
- Missing authorization in PostgreSQL built-in views pg_stats_ext and pg_stats_ext_exprs allows an
unprivileged database user to read most common values and other statistics from CREATE STATISTICS
commands of other users. The most common values may reveal column values the eavesdropper could not
otherwise read or results of functions they cannot execute. Installing an unaffected version only fixes
fresh PostgreSQL installations, namely those that are created with the initdb utility after installing
that version. Current PostgreSQL installations will remain vulnerable until they follow the instructions
in the release notes. Within major versions 14-16, minor versions before PostgreSQL 16.3, 15.7, and
14.12 are affected. Versions before PostgreSQL 14 are unaffected. (CVE-2024-4317)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
