{"id":"PYSEC-2022-26","details":"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.","aliases":["CVE-2022-23607","GHSA-fhpf-pp6p-55qc"],"modified":"2023-11-08T04:08:24.827076Z","published":"2022-02-01T11:15:00Z","references":[{"type":"ADVISORY","url":"https://github.com/twisted/treq/security/advisories/GHSA-fhpf-pp6p-55qc"}],"affected":[{"package":{"name":"treq","ecosystem":"PyPI","purl":"pkg:pypi/treq"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"21.1.0"},{"fixed":"22.1.0"}]}],"versions":["21.1.0","21.5.0"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/treq/PYSEC-2022-26.yaml"}}],"schema_version":"1.7.3"}
