How to Fix CVE-2025-58065

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: 4.8.1 
pip install flask-appbuilder>=4.8.1
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-2025-58065, 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 4.8.1), 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-287: Improper Authentication, where when an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. 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 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
