Descriptions

The Ultimate Member – User Profile, User Registration, Login & Membership Plugin WordPress plugin before 2.1.20 did not properly sanitise, validate or encode the query string when generating a link to edit user's own profile, leading to an authenticated reflected Cross-Site Scripting issue. Knowledge of the targeted username is required to exploit this, and attackers would then need to make the related logged in user open a malicious link.

El plugin de WordPress Ultimate Member - User Profile, User Registration, Login & Membership Plugin versión anterior a 2.1.20, no saneaba, validaba ni codificaba apropiadamente la cadena de consulta cuando genera un enlace para editar el perfil del usuario, lo que generaba un problema de tipo Cross-Site Scripting reflejado autenticado. Es requerido el conocimiento del nombre de usuario objetivo para explotar esto, y los atacantes tendrían que hacer que el usuario conectado relacionado abra un enlace malicioso
