## What is CVE-2026-12736?

CVE-2026-12736 is a high-severity vulnerability in WPify Woo – Withdrawal, CRN/VAT, QR payments, Heureka and more for WooCommerce, published on 24 Jul 2026. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

The Wpify Woo plugin for WordPress is vulnerable to Privilege Escalation in versions up to, and including, 5.4.16. This is due to the SettingsApi::save_option() REST route (POST /wp-json/wpify-woo/v1/option) passing the request-supplied 'option' and 'data' parameters directly to update_option() without any option-name allowlist or value sanitization, while the permission_callback only verifies the manage_woocommerce capability. This makes it possible for authenticated attackers, with Shop Manager-level access and above, to elevate their privileges to Administrator by overwriting arbitrary WordPress options (for example setting default_role to administrator and users_can_register to 1, or disabling security plugins via active_plugins).

Weakness: CWE-269 (Improper Privilege Management)
