CVE-2026-15014
The SMS Alert – SMS & OTP for WooCommerce, Order Notifications & Abandoned Cart Recovery plugin for WordPress is vulnerable to Authentication Bypass leading to Account Takeover in all versions up to, and including, 3.9.7 via the `billing_phone` parameter. This is due to the `processRegistration()` function using a phone-unbound `$_SESSION['sa_mobile_verified']` boolean flag as the sole gate before issuing an authentication cookie — the flag is set to `true` after any successful OTP validation without being bound to the specific phone number that was verified. This makes it possible for unauthenticated attackers to complete OTP verification for a phone number they control, then resubmit the registration request with a victim's `billing_phone` value to have `wp_set_auth_cookie()` called for the resolved victim account, enabling full authentication as any existing WordPress user whose registered phone number is known or guessable, including administrators.
No public exploitation has been reported so far. No distribution fix is listed yet; apply vendor mitigations and monitor.
Recommended action: Track your distribution's security tracker and apply the fix as soon as it ships.
