How to Fix CVE-2022-23607

To remediate this vulnerability, upgrade all affected Treq dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

treq fixed: 22.1.0 
pip install treq>=22.1.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show treq

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2022-23607, inspect your installed packages using pip:

pip show treq

Analyze the terminal output to locate any version of Treq in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 22.1.0), your application is affected.

Note: The pip show treq command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-425: Direct Request ('Forced Browsing'), where the web application does not adequately enforce appropriate authorization on all restricted urls, scripts, or files. In Treq, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact Treq's request methods (`treq.get`, `treq.post`, `HTTPClient.request`, `HTTPClient.get`, etc.) accept cookies as a dictionary, for example: ```py treq.get('https://example.com/', cookies={'session': '1234'}) ``` 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`. ### Patches 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. ### Workarounds Instead of passing a dictionary as the *cookies* argument, pass a `http.cookiejar.CookieJar` instance with properly domain- and scheme-scoped cookies in it: ```py from http.cookiejar import CookieJar from requests.cookies import create_cookie jar = CookieJar() jar.add_cookie( create_cookie( name='session', value='1234', domain='example.com', secure=True, ), ) client = HTTPClient(cookies=jar) client.get('https://example.com/') ``` ### References * Originally reported at [huntr.dev](https://huntr.dev/bounties/3c9204fc-a3d1-4441-8599-924c5f57e7ae/?token=06d930e37046c914bcb037e85cc227dc7b510b475989fc69837566562ba899277d46b0fb4b1e21cdcb6ddc1b7d9b1ded632cf3a3551ecb89afca16a63b34641284b50479d5195bba2ac09b116f3dd4fad27f54404c2de922c05c8c8b744aec27bb4d4d198cb8b3abf479af0c2d5fbaa10412da7922594ac3eb39) * A related issue in the handling of HTTP basic authentication was addressed in Twisted 22.1 ([GHSA-92x2-jw7w-xvvx](https://github.com/twisted/twisted/security/advisories/GHSA-92x2-jw7w-xvvx), CVE-2022-21712).
