      "value": "Vikunja is an open-source self-hosted task management platform. Prior to version 2.2.0, a flaw in Vikunja’s password reset logic allows disabled users to regain access to their accounts. The `ResetPassword()` function sets the user’s status to `StatusActive` after a successful password reset without verifying whether the account was previously disabled. By requesting a reset token through `/api/v1/user/password/token` and completing the reset via `/api/v1/user/password/reset`, a disabled user can reactivate their account and bypass administrator-imposed account disablement. Version 2.2.0 patches the issue."

Antes de la versión 2.2.0, una falla en la lógica de restablecimiento de contraseña de Vikunja permite a los usuarios deshabilitados recuperar el acceso a sus cuentas. La función 'ResetPassword()' establece el estado del usuario en 'StatusActive' después de un restablecimiento de contraseña exitoso sin verificar si la cuenta había sido deshabilitada previamente. Al solicitar un token de restablecimiento a través de '/api/v1/user/password/token' y completar el restablecimiento a través de '/api/v1/user/password/reset', un usuario deshabilitado puede reactivar su cuenta y eludir la deshabilitación de cuenta impuesta por el administrador. La versión 2.2.0 corrige el problema."
