CVE-2023-49856Network attack vector

Authenticated code execution via unchecked option updates

Published Dec 9, 2024 · Updated May 11, 2026

Missing authorization in Smart Forms 2.6.84 and earlier allows remote authenticated users to modify arbitrary WordPress options. The smart_forms_save_settings() AJAX handler accepts an option name and value, then updates that WordPress option without a capability check or plugin-option allowlist. Subscriber-level access reaches the handler, and option changes can enable remote code execution.
