[15.0] Failure to export to XLSX/CSV

[dieg0-a]

Impacted versions: v15 (at least from 05/13/22 to 06/20/22 nightly releases)

Steps to reproduce: Try to export product data, so far trying to export other data also results in an error

Current behavior: The frontend displays the following error message:

TypeError: invalid parameter format
    at Object.parse (http://localhost:8069/web/assets/99-c254acb/web.assets_common.min.js:4547:45)
    at XMLHttpRequest.xhr.onload (http://localhost:8069/web/assets/99-c254acb/web.assets_common.min.js:4678:241)

Expected behavior: File save dialog should pop up

Observations: Based on my research a string containing (product.template) is passed to contentDisposition.parse() and that results in PARAM_REGEXP not matching up to the end of the string, instead it stops as soon as it finds a "(", which results in an exception as per:

[addons/web/static/src/legacy/js/libs/content-disposition.js]

if (index !== -1 && index !== string.length) {
--
215 | throw new TypeError('invalid parameter format')

Removing this check works around the problem but the resulting file name appears to be missing something at the end, ie:
Product template_.xlsx

It doesn't look like the backend is catching any errors as there are no error or warning messages in the server log.

We had the same issue right now on an on-premise server. We have found that the problem was caused by a wrong version of the python module "Werkzeug", which was too new. The problem of the error message above was that the filename was not created correctly, in a way, that the brackets were not escaped.
