Description
The User Verification by PickPlugins plugin for WordPress is vulnerable to authentication bypass in all versions up to, and including, 2.0.46. This is due to the use of a loose PHP comparison operator to validate OTP codes in the "user_verification_form_wrap_process_otpLogin" function. This makes it possible for unauthenticated attackers to log in as any user with a verified email address, such as an administrator, by submitting a "true" OTP value.
