In Redash version 10.0 and prior, the implementation of Google Login (via OAuth) incorrectly uses the `state` parameter to pass the next URL to redirect the user to after login. The `state` parameter should be used for a Cross-Site Request Forgery (CSRF) token, not a static and easily predicted value. This vulnerability does not affect users who do not use Google Login for their instance of Redash. A patch in the `master` and `release/10.x.x` branches addresses this by replacing `Flask-Oauthlib` with `Authlib` which automatically provides and validates a CSRF token for the state variable. The new implementation stores the next URL on the user session object. As a workaround, one may disable Google Login to mitigate the vulnerability."}, {"lang": "es", "value": "Redash es un paquete para visualizar y compartir datos. En la versi\u00f3n 10.0 de Redash y anteriores, la implementaci\u00f3n de Google Login (por medio de OAuth) usa incorrectamente el par\u00e1metro \"state\" para pasar la siguiente URL a la que redirigir al usuario despu\u00e9s de iniciar sesi\u00f3n.

Un parche en las ramas \"master\" y \"release/10.x.x\" aborda esto sustituyendo \"Flask-Oauthlib\" por \"Authlib\" que proporciona y comprueba autom\u00e1ticamente un token CSRF para la variable de estado.
