Advisory

Source description from Wordfence Intelligence, credited to Peng Zhou.

The SMS Alert – SMS & OTP for WooCommerce, Order Notifications & Abandoned Cart Recovery plugin for WordPress is vulnerable to Privilege Escalation in versions up to, and including, 3.9.4. This is due to missing validation that the phone number supplied at login matches the phone number that was OTP-verified in the session, allowing session token reuse across arbitrary accounts. This makes it possible for authenticated attackers, with subscriber-level access and above, to log in as any user, including administrators, without knowing the account's password by supplying an arbitrary username after completing OTP verification for a different phone number.
