  - An unauthenticated attacker can make get_page_template() page-template resolution include a chosen
    readable local .php file outside the active theme directories. If relevant pre-conditions for both the
    server and the active theme are met, this can lead to RCE. (CVE-2026-87902)

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