"The version of PostgreSQL installed on the remote host is 13 prior to 13.22, 14 prior to 14.19, 15 prior to 15.14, 16
prior to 16.10, or 17 prior to 17.6. As such, it is potentially affected by multiple vulnerabilities :

  - Improper neutralization of newlines in pg_dump in PostgreSQL allows a user of the origin server to inject
    arbitrary code for restore-time execution as the client operating system account running psql to restore
    the dump, via psql meta-commands inside a purpose-crafted object name. The same attacks can achieve SQL
    injection as a superuser of the restore target server. pg_dumpall, pg_restore, and pg_upgrade are also
    affected. Versions before PostgreSQL 17.6, 16.10, 15.14, 14.19, and 13.22 are affected. Versions before
    11.20 are unaffected. CVE-2012-0868 had fixed this class of problem, but version 11.20 reintroduced it.
    (CVE-2025-8715)

  - Untrusted data inclusion in pg_dump in PostgreSQL allows a malicious superuser of the origin server to
    inject arbitrary code for restore-time execution as the client operating system account running psql to
    restore the dump, via psql meta-commands. pg_dumpall is also affected. pg_restore is affected when used to
    generate a plain-format dump. This is similar to MySQL CVE-2024-21096. Versions before PostgreSQL 17.6,
    16.10, 15.14, 14.19, and 13.22 are affected. (CVE-2025-8714)

  - PostgreSQL optimizer statistics allow a user to read sampled data within a view that the user cannot
    access. Separately, statistics allow a user to read sampled data that a row security policy intended to
    hide. PostgreSQL maintains statistics for tables by sampling data available in columns; this data is
    consulted during the query planning process. Prior to this release, a user could craft a leaky operator
    that bypassed view access control lists (ACLs) and bypassed row security policies in partitioning or table
    inheritance hierarchies. Reachable statistics data notably included histograms and most-common-values
    lists. CVE-2017-7484 and CVE-2019-10130 intended to close this class of vulnerability, but this gap
    remained. Versions before PostgreSQL 17.6, 16.10, 15.14, 14.19, and 13.22 are affected. (CVE-2025-8713)

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