A flaw was found in python-werkzeug. Browsers may allow “nameless” cookies 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 for another subdomain. If a Werkzeug application is running next to a vulnerable or malicious subdomain that sets such a cookie using a vulnerable browser, the Werkzeug application will see the bad cookie value but the valid cookie key.
