How to Fix CVE-2024-45314

To remediate this vulnerability, upgrade all affected Flask appbuilder dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

flask-appbuilder fixed: 4.5.1 
pip install flask-appbuilder>=4.5.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show flask-appbuilder

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2024-45314, inspect your installed packages using pip:

pip show flask-appbuilder

Analyze the terminal output to locate any version of Flask appbuilder in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.5.1), your application is affected.

Note: The pip show flask-appbuilder command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-525: Use of Web Browser Cache Containing Sensitive Information, where the web application does not use an appropriate caching policy that specifies the extent to which each web page and associated form fields should be cached. In Flask appbuilder, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact 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. ### Patches Upgrade flask-appbuilder to version 4.5.1 ### Workarounds If upgrading is not possible configure your web server to send the following HTTP headers for /login: "Cache-Control": "no-store, no-cache, must-revalidate, max-age=0" "Pragma": "no-cache" "Expires": "0"
