Werkzeug 3.x incompatible with Flask 0.10.1

High Severity

The upgrade to werkzeug>=3.1.5 is incompatible with Flask==0.10.1. Werkzeug 3.0 introduced major breaking changes (like removing url_quote from werkzeug.urls) that break all Flask versions prior to 3.x. The application will crash at startup with an ImportError. Either Flask needs to be upgraded to version 3.x, or werkzeug needs to stay at 2.x despite the security vulnerability.
