Redash is a package for data visualization and sharing. If an admin sets up Redash versions 10.0.0 and prior without explicitly specifying the REDASHCOOKIESECRET or REDASHSECRETKEY environment variables, a default value is used for both that is the same across all installations. In such cases, the instance is vulnerable to attackers being able to forge sessions using the known default value. This issue only affects installations where the REDASHCOOKIESECRET or REDASHSECRETKEY environment variables have not been explicitly set. This issue does not affect users of the official Redash cloud images, Redash's Digital Ocean marketplace droplets, or the scripts in the getredash/setup repository. These instances automatically generate unique secret keys during installation. One can verify whether one's instance is affected by checking the value of the REDASHCOOKIESECRET environment variable. If it is c292a0a3aa32397cdb050e233733900f, should follow the steps to secure the instance, outlined in the GitHub Security Advisory.
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.
