Headline
GHSA-32ff-4g79-vgfc: Flask-AppBuilder before v4.1.3 allows inference of sensitive information through query strings
Impact
An authenticated Admin user could craft HTTP requests to filter users by their salted and hashed passwords strings. These filters could be made by using partial hashed password strings. The response would not include the hashed passwords, but an attacker could infer partial password hashes and their respective users.
Only when using AUTH_DB database authentication option.
Patches
Fixed on 4.1.3
