Advisory
Source description from Wordfence Intelligence, credited to Peter Tang.
The OTP Login With Phone Number, OTP Verification plugin for WordPress is vulnerable to Account Takeover in all versions up to, and including, 1.8.78. This is due to missing capability check in lwp_update_phonenumber_field() allowing any authenticated user to set or overwrite the phone_number user meta used as a login credential. This makes it possible for authenticated attackers, with subscriber-level access and above, to self-assign another user's registered phone number and authenticate as that user via OTP login.
