CVE-2026-14345 is a remote code execution vulnerability in the WPFunnels – Funnel Builder for WooCommerce with Checkout & One Click Upsell plugin for WordPress affecting all versions up to and including 3.12.7. The flaw is triggered via the postData parameter. Attacker-controlled postData values are written to a .log file without proper sanitization, and that log file is later rendered by the plugin using include_once in wpfnl_show_log. Because the log file is PHP-includeable, an attacker can inject PHP code into the log and have it executed when the file is viewed through the plugin interface. The injection step is reachable without authentication because the nonce required for the opt-in endpoint is publicly emitted on funnel step pages.
