"The version of PostgreSQL installed on the remote host is 13 prior to 13.19, 14 prior to 14.16, 15 prior to 15.11, 16
prior to 16.7, or 17 prior to 17.3. As such, it is potentially affected by a vulnerability :

  - Improper neutralization of quoting syntax in PostgreSQL libpq functions PQescapeLiteral(),
    PQescapeIdentifier(), PQescapeString(), and PQescapeStringConn() allows a database input provider to
    achieve SQL injection in certain usage patterns. Specifically, SQL injection requires the application to
    use the function result to construct input to psql, the PostgreSQL interactive terminal. Similarly,
    improper neutralization of quoting syntax in PostgreSQL command line utility programs allows a source of
    command line arguments to achieve SQL injection when client_encoding is BIG5 and server_encoding is one of
    EUC_TW or MULE_INTERNAL. Versions before PostgreSQL 17.3, 16.7, 15.11, 14.16, and 13.19 are affected.
    (CVE-2025-1094)

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