Administrator access via exposed OTP response

Published Jan 23, 2023 · Updated Apr 2, 2025

Authentication bypass in PickPlugins User Verification before 1.0.94 allows remote attackers to obtain an administrator's OTP. The unauthenticated user_verification_send_otp AJAX action returns the generated login code in its HTTP response when given a username. Knowing a public administrator username is sufficient to retrieve that code and sign in with administrator privileges.
