Overview

Flask-AppBuilder is a simple and rapid application development framework, built on top of Flask. includes detailed security, auto CRUD generation for your models, google charts and much more.

Affected versions of this package are vulnerable to Information Exposure. Attackers were able to masquerade as an authenticated user through OAuth providers. The fix changes the ID that is used to link a google login to an account to an immutable user ID that is provided by google. The previous implementation used the display name, which could easily be changed at any point and used to log in to a different account by an attacker.
