Prior to 5.0.6, in modules/events/events_function.php, the event participation logic allows any user who can participate in an event to register OTHER users by manipulating the user_uuid GET parameter. The condition uses || (OR), meaning if possibleToParticipate() returns true (event is open for participation), ANY user - not just leaders - can specify a different user_uuid and register/cancel participation for that user. The code then operates on $user->getValue('usr_id') (the target user from user_uuid) rather than the current user. This vulnerability is fixed in 5.0.6."},{"lang":"es","value":"Admidio es una solución de gestión de usuarios de código abierto. Antes de la 5.0.6, en modules/events/events_function.php, la lógica de participación en eventos permite a cualquier usuario que pueda participar en un evento registrar a OTROS usuarios manipulando el parámetro GET user_uuid. La condición utiliza || (OR), lo que significa que si possibleToParticipate() devuelve verdadero (el evento está abierto para la participación), CUALQUIER usuario - no solo los líderes - puede especificar un user_uuid diferente y registrar/cancelar la participación para ese usuario.
