What the vulnerability does
01Description
Querybook is an open source data querying UI. In affected versions user provided data is not escaped in the error field of the auth callback url in `querybook/server/app/auth/oauth_auth.py` and `querybook/server/app/auth/okta_auth.py`. This may allow attackers to perform reflected cross site scripting (XSS) if Content Security Policy (CSP) is not enabled or `unsafe-inline` is allowed. Users are advised to upgrade to the latest, patched version of querybook (version 3.14.2 or greater). Users unable to upgrade may enable CSP and not allow unsafe-inline or manually escape query parameters in a reverse proxy.
