CVE-2022-23607

Name	CVE-2022-23607
Description	treq is an HTTP library inspired by requests but written on top of Twisted's Agents. Treq's request methods (`treq.get`, `treq.post`, etc.) and `treq.client.HTTPClient` constructor accept cookies as a dictionary. Such cookies are not bound to a single domain, and are therefore sent to every domain ("supercookies"). This can potentially cause sensitive information to leak upon an HTTP redirect to a different domain., e.g. should `https://example.com` redirect to `http://cloudstorageprovider.com` the latter will receive the cookie `session`. Treq 2021.1.0 and later bind cookies given to request methods (`treq.request`, `treq.get`, `HTTPClient.request`, `HTTPClient.get`, etc.) to the origin of the url parameter. Users are advised to upgrade. For users unable to upgrade Instead of passing a dictionary as the cookies argument, pass a `http.cookiejar.CookieJar` instance with properly domain- and scheme-scoped cookies in it.
