How to fix?

Upgrade Alpine:3.20 py3-werkzeug to version 2.2.2-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream py3-werkzeug package and not the py3-werkzeug package as distributed by Alpine. See How to fix? for Alpine:3.20 relevant fixed versions and status.

Improper parsing of HTTP requests in Pallets Werkzeug v2.1.0 and below allows attackers to perform HTTP Request Smuggling using a crafted HTTP request with multiple requests included inside the body. NOTE: the vendor's position is that this behavior can only occur in unsupported configurations involving development mode and an HTTP server from outside the Werkzeug project
