CVE-2022-23607

Advisory

Treq 22.1.0 includes a fix for CVE-2022-23607: 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 22.1.0 and later bind cookies given to request methods ('treq.request', 'treq.get', 'HTTPClient.request', 'HTTPClient.get', etc.) to the origin of the *url* parameter. 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.

===================

Bugfixes
--------

- Cookies specified as a dict were sent to every domain, not just the domain of the request, potentially exposing them on redirect. See `GHSA-fhpf-pp6p-55qc <https://github.com/twisted/treq/security/advisories/GHSA-fhpf-pp6p-55qc>`_. (`#339 <https://github.com/twisted/treq/issues/339>`__)
