CVE-2021-43777 Information

Description

Redash is a package for data visualization and sharing. 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.
