Vulnerability Description

Flask-AppBuilder is an application development framework built on top of Flask python framework. In versions prior to 4.1.3 an authenticated Admin user could query other users by their salted and hashed passwords strings. These filters could be made by using partial hashed password strings.

Users are advised to upgrade. There are no known workarounds for this issue.
