Subscriber privilege escalation via unrestricted JSON import
Published Dec 18, 2025 · Updated Dec 18, 2025
Incorrect privilege assignment in Jthemes ImmiEx 1.5.8 and earlier allows remote authenticated users to elevate WordPress privileges. The immiex_import_json AJAX handler accepts imported JSON without an administrator-only authorization gate, CSRF check, input validation, or an option allowlist. Subscriber-level access is sufficient to invoke the handler and change protected WordPress settings, producing higher application privileges.
