GHSA-765j-9r45-w2q2: Flask App Builder has an Authentication Bypass vulnerability when using non AUTH_DB methods

Impact

When Flask-AppBuilder is configured to use OAuth, LDAP, or other non-database authentication methods, the password reset endpoint remains registered and accessible, despite not being displayed in the user interface. This allows an enabled user to reset their password and be able to create JWT tokens even after the user is disabled on the authentication provider.

Patches

Upgrade to Flask-AppBuilder version 4.8.1 or later

Workarounds

If immediate upgrade is not possible:

Manually disable password reset routes in the application configuration
Implement additional access controls at the web server or proxy level to block access to the reset my password URL.
Monitor for suspicious password reset attempts from disabled accounts
