CVE-2026-14281
CriticalCVSS 9.8Summary
The Automation Web Platform – Notifications and OTP for WooCommerce, Advanced Country Code plugin for WordPress (up to and including 4.8.6) is vulnerable to privilege escalation due to missing permission enforcement on the publicly accessible REST route `POST /wp-json/wawp/v1/signup/<op>` and the absence of a key allowlist in the `finish_registration_logic` function. The attacker-controlled `wawp_custom_fields` parameter is copied directly into `update_user_meta()`, allowing sensitive meta keys such as `wp_capabilities` and `wp_user_level` to be set. This enables unauthenticated attackers to register an account with the administrator role and gain full administrative access. When OTP verification is enabled, the OTP session token is returned in plaintext in the HTTP response, and the `handle_magic_link_request()` handler marks it as verified on any unauthenticated GET request containing it without checking the OTP code, making the OTP step trivially bypassable.
Risk Assessment
Attackers can gain full administrative control over the WordPress site, leading to complete site takeover, data theft, and potential malware installation.
Recommendation
Immediately update the plugin to a version newer than 4.8.6. If update is not possible, disable the public REST route `/wp-json/wawp/v1/signup/<op>` or implement additional authorization checks and a meta key allowlist.

Original NVD description (English source)
The Automation Web Platform – Notifications and OTP for WooCommerce, Advanced Country Code plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 4.8.6. This is due to missing permission enforcement on the publicly accessible REST route `POST /wp-json/wawp/v1/signup/<op>` and the absence of a key allowlist in the `finish_registration_logic` function, which copies the attacker-controlled `wawp_custom_fields` parameter directly into `update_user_meta()` — allowing sensitive meta keys such as `wp_capabilities` and `wp_user_level` to be set by the caller. This makes it possible for unauthenticated attackers to register a new account with the administrator role and gain full administrative access to the site. When OTP verification is enabled at signup, the OTP session token (`otp_transient`) is returned in plaintext in the HTTP response body, and the `handle_magic_link_request()` handler marks that token as verified on any unauthenticated GET request containing it without ever checking the OTP code value — making the OTP step trivially bypassable with no inbox or SMS access required.
