Recently, Werkzeug 1.* has been flagged for vulnerabilities by Safety. This is causing our GitHub Actions workflows to fail:

The vulnerability is as follows:

        {
            "advisory": "Werkzeug version 2.0.2 improves the security of the debugger cookies. \"SameSite\" attribute is set to \"Strict\" instead of \"None\", and the secure flag is added when on HTTPS.",
            "cve": "PVE-2021-42050",
            "id": "pyup.io-42050",
            "specs": [
                "<2.0.2"
            ],
            "v": "<2.0.2"
        },

We need to either migrate to Flask/Werkzeug 2.0 (a substantial project), or add an exception for this in our pipeline.
