Incompatible Werkzeug upgrade breaks Flask 0.10.1

High Severity

Upgrading Werkzeug from 0.9.4 to 3.1.5 while keeping Flask==0.10.1 causes a breaking incompatibility. Flask 0.10.1 (from 2013) relies on Werkzeug 0.x internal APIs that were removed or moved in Werkzeug 3.x. This will cause immediate import errors (e.g., cannot import name 'url_quote' from 'werkzeug.urls') and prevent the application from starting. Flask needs to be upgraded to at least version 2.x or 3.x to work with Werkzeug 3.1.5.
