🛡️ WordPress Form Protection Plugin — Yandex SmartCaptcha (Smart Captcha) (v1.5.3.5)

A ready-to-use security plugin for WordPress that protects all key forms from bots and spam using Yandex SmartCaptcha.
Supports both visible and invisible (auto-submit) captcha modes.

⚙️ Supported Modules

✅ Gravity Forms – automatic SmartCaptcha insertion before the submit button.
✅ Contact Form 7 – spam blocking, captcha displayed before submission.
✅ WooCommerce – login and registration forms on the My Account page.
✅ WordPress Login / Register – native wp-login.php and wp-register.php pages.
✅ Elementor Pro Forms – server-side token validation.
✅ Shortcode [ysc_smartcaptcha] – use anywhere in your custom forms or themes.
✅ Comments & WooCommerce Reviews – full protection and automatic scroll back to the form if validation fails.
✅ Invisible Mode – fully automatic captcha execution without user clicks.

🚀 What’s New in Version 1.5.3.2

New frontend engine with a unified YSC_DATA namespace.
Chained onload callbacks (no overwriting of window.yscOnloadFunction).
Added anti-loop flag __yscSubmitting to prevent double submits.
Token is now mandatory for all captcha types (no “first try” bypass).
Full support for dynamic / popup / off-canvas forms.
Built-in user error notifications (toast pop-ups).
Automatic JS/CSS loading when shortcode [ysc_smartcaptcha] is detected in content.
Cache-plugin safe — excludes smartcaptcha, YSC_DATA, and yscOnloadFunction.
Better Elementor/WooCommerce layout handling for invisible mode.
Added DNS-prefetch and strict Referrer-Policy headers for faster loading.

🔒 How It Works

The plugin injects a SmartCaptcha widget and hidden smart-token input.
After the user passes the captcha, Yandex returns a verification token.
The server validates the token via Yandex’s official API (secret, token, ip).
Invalid or expired tokens are blocked; the user sees a clear message in the form.
Works even with asynchronous or combined JS loading.
