Description
The SMS Alert Order Notifications plugin for WordPress is vulnerable to Privilege Escalation in versions up to, and including, 3.9.7. This is due to a shared OTP session key (sa_mobile_verified) across all form handlers combined with an insufficient phone number check (strpos rather than strict equality, and no requirement for sa_mobile to be set) in the WooCommerce registration handler, allowing cross-form session reuse to bypass phone ownership verification. This makes it possible for unauthenticated attackers to log in as any existing user whose phone number is known by completing OTP verification on any other integrated form handler and then submitting the WooCommerce registration form with the victim's phone number.
