GHSA-fw5r-6m3x-rh7p: flask-appbuilder (CVE-2024-45314)

Package	Ecosystem	Affected	Fixed in
flask-appbuilder	PyPI	<4.5.1	4.5.1

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Flask-AppBuilder versions before 4.5.1 have a login form that lets browsers cache sensitive fields, so credentials may be stored locally on shared computers. An attacker would need access to the same browser or machine, and the advisory does not describe any remote exploitation. Upgrade flask-appbuilder to 4.5.1; if upgrading is not possible, configure the web server to send no-store, no-cache cache headers for the /login page.
