Description

Flask-AppBuilder is an application development framework. Prior to version 4.5.1, the auth DB login form default cache directives allows browser to locally store sensitive data. This can be an issue on environments using shared computer resources. Version 4.5.1 contains a patch for this issue. If upgrading is not possible, configure one's web server to send the specific HTTP headers for /login per the directions provided in the GitHub Security Advisory.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for flask-appbuilder, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update flask-appbuilder to 4.5.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-45314 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
