Information Exposure Through Browser Caching

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 Through Browser Caching due to the default cache directives of the auth DB login form, allowing sensitive data to be stored locally by the browser. An attacker can access the sensitive data stored locally by exploiting shared computer environments.

How to fix Information Exposure Through Browser Caching?

Improper Authentication

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 Improper Authentication due to incorrect authentication handling when using the AUTH_OID auth type. An attacker can forge an HTTP request to deceive the backend into using any requested OpenID service, potentially granting unauthorized privilege access if a custom OpenID service is deployed by the attacker and accessible by the backend.

Note:

This is only exploitable when the application uses the old OpenID 2.0 authorization protocol, which is considered legacy and has been deprecated for over a decade.
