The JAY Login & Register plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 2.4.01. This is due to incorrect authentication checking in the 'jay_login_register_process_switch_back' function with the 'jay_login_register_process_switch_back' cookie value. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the user id.
The JAY Login & Register plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 2.4.01. This is due to incorrect authentication checking in the 'jay_login_register_process_switch_back' function with the 'jay_login_register_process_switch_back' cookie value. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the user id.
El plugin JAY Login & Register para WordPress es vulnerable a omisión de autenticación en versiones hasta la 2.4.01, inclusive. Esto se debe a una comprobación de autenticación incorrecta en la función 'jay_login_register_process_switch_back' con el valor de la cookie 'jay_login_register_process_switch_back'. Esto hace posible que atacantes no autenticados inicien sesión como cualquier usuario existente en el sitio, como un administrador, si tienen acceso al ID de usuario.
