Parse a cookie. Either from a string or WSGI environ · Per default encoding errors are ignored. If you want a different behavior you can set errors to 'replace' or 'strict'. In strict mode a HTTPUnicodeError is raised

I decided to see what other platforms had this same or similar issue. Although Flask does not do URL decoding as with the Ruby platform it does unquote both the cookie name and value.

Browsers may allow "nameless" cookies that look like =value instead of key=value. A vulnerable browser may allow a compromised application on an adjacent subdomain to exploit this to set a cookie like =__Host-test=bad for another subdomain. Werkzeug <= 2.2.2 will parse the cookie =__Host-test=bad as __Host-test=bad.

April 29, 2023 - [#1060](https://github.com/pallets/werkzeug/issues/1060), [#1680](https://github.com/pallets/werkzeug/issues/1680) - The cookie_jar attribute is deprecated. http.cookiejar is no longer used for storage. - Domain and path matching is used when sending cookies in requests. The domain and path parameters default to localhost and /. - Added a get_cookie method to inspect cookies. - Cookies have decoded_key and decoded_value attributes to match what the app sees rather than the encoded values a client would see.
