      "value": "LORIS (Longitudinal Online Research and Imaging System) is a self-hosted web application that provides data- and project-management for neuroimaging research. Prior to 27.0.3 and 28.0.1, the redirect parameter upon login to LORIS was not validating the value of the redirect as being within LORIS, which could be used to trick users into visiting arbitrary URLs if they are given a link with a third party redirect parameter. This vulnerability is fixed in 27.0.3 and 28.0.1."

      "value": "LORIS (Longitudinal Online Research and Imaging System) es una aplicación web autoalojada que proporciona gestión de datos y proyectos para la investigación en neuroimagen. Antes de las versiones 27.0.3 y 28.0.1, el parámetro de redirección al iniciar sesión en LORIS no estaba validando que el valor de la redirección estuviera dentro de LORIS, lo que podría usarse para engañar a los usuarios para que visitaran URLs arbitrarias si se les proporcionaba un enlace con un parámetro de redirección de terceros. Esta vulnerabilidad está corregida en las versiones 27.0.3 y 28.0.1."
