CVE-2022-24776Network attack vector

Open redirect via unchecked next parameter

Published Mar 24, 2022 · Updated Apr 23, 2025

Open redirect in Flask-AppBuilder before 3.4.5 allows remote attackers to send users to an external site after database login. Login handlers pass the untrusted next query parameter directly to Flask redirect without validating its scheme or host. Exploitation requires a victim to follow a crafted application URL and complete a database-authentication login, after which the browser leaves the trusted origin.
