CVE-2023-32681

Impact

Since Requests v2.3.0, Requests has been vulnerable to potentially leaking Proxy-Authorization headers to destination servers, specifically during redirects to an HTTPS origin. This is a product of how rebuild_proxies is used to recompute and reattach the Proxy-Authorization header to requests when redirected. Note this behavior has only been observed to affect proxied requests when credentials are supplied in the URL user information component (e.g. https://username:password@proxy:8080).

Current vulnerable behavior(s):

1. HTTP → HTTPS: leak
2. HTTPS → HTTP: no leak
3. HTTPS → HTTPS: leak
4. HTTP → HTTP: no leak

For HTTP connections sent through the proxy, the proxy will identify the header in the request itself and remove it prior to forwarding to the destination server. However when sent over HTTPS, the Proxy-Authorization header must be sent in the CONNECT request as the proxy has no visibility into further tunneled requests. This results in Requests forwarding the header to the destination server unintentionally, allowing a malicious actor to potentially exfiltrate those credentials.

The reason this currently works for HTTPS connections in Requests is the Proxy-Authorization header is also handled by urllib3 with our usage of the ProxyManager in adapters.py with proxy_manager_for. This will compute the required proxy headers in proxy_headers and pass them to the Proxy Manager, avoiding attaching them directly to the Request object. This will be our preferred option going forward for default usage.

Patches

Starting in Requests v2.31.0, Requests will no longer attach this header to redirects with an HTTPS destination. This should have no negative impacts on the default behavior of the library as the proxy credentials are already properly being handled by urllib3's ProxyManager.

For users with custom adapters, this may be potentially breaking if you were already working around this behavior. The previous functionality of rebuild_proxies doesn't make sense in any case, so we would encourage any users impacted to migrate any handling of Proxy-Authorization directly into their custom adapter.

Workarounds

For users who are not able to update Requests immediately, there is one potential workaround.

You may disable redirects by setting allow_redirects to False on all calls through Requests top-level APIs. Note that if you're currently relying on redirect behaviors, you will need to capture the 3xx response codes and ensure a new request is made to the redirect destination.

import requests
r = requests.get('http://github.com/', allow_redirects=False)

CVE-2024-35195

When using a requests.Session, if the first request to a given origin is made with verify=False, TLS certificate verification may remain disabled for all subsequent requests to that origin, even if verify=True is explicitly specified later.

This occurs because the underlying connection is reused from the session's connection pool, causing the initial TLS verification setting to persist for the lifetime of the pooled connection. As a result, applications may unintentionally send requests without certificate verification, leading to potential man-in-the-middle attacks and compromised confidentiality or integrity.

This behavior affects versions of requests prior to 2.32.0.

CVE-2024-47081

Impact

Due to a URL parsing issue, Requests releases prior to 2.32.4 may leak .netrc credentials to third parties for specific maliciously-crafted URLs.

Workarounds

For older versions of Requests, use of the .netrc file can be disabled with trust_env=False on your Requests Session (docs).

CVE-2026-25645

Impact

The requests.utils.extract_zipped_paths() utility function uses a predictable filename when extracting files from zip archives into the system temporary directory. If the target file already exists, it is reused without validation. A local attacker with write access to the temp directory could pre-create a malicious file that would be loaded in place of the legitimate one.

Affected usages

Standard usage of the Requests library is not affected by this vulnerability. Only applications that call extract_zipped_paths() directly are impacted.

Remediation

Upgrade to at least Requests 2.33.0, where the library now extracts files to a non-deterministic location.

If developers are unable to upgrade, they can set TMPDIR in their environment to a directory with restricted write access.

Release Notes

psf/requests (requests)

v2.33.0

Compare Source

Announcements

• 📣 Requests is adding inline types. If you have a typed code base that
  uses Requests, please take a look at #​7271. Give it a try, and report
  any gaps or feedback you may have in the issue. 📣

Security

• CVE-2026-25645 requests.utils.extract_zipped_paths now extracts
  contents to a non-deterministic location to prevent malicious file
  replacement. This does not affect default usage of Requests, only
  applications calling the utility function directly.

Improvements

• Migrated to a PEP 517 build system using setuptools. (#​7012)

Bugfixes

• Fixed an issue where an empty netrc entry could cause
  malformed authentication to be applied to Requests on
  Python 3.11+. (#​7205)

Deprecations

• Dropped support for Python 3.9 following its end of support. (#​7196)

Documentation

• Various typo fixes and doc improvements.

v2.32.5

Compare Source

Bugfixes

• The SSLContext caching feature originally introduced in 2.32.0 has created
  a new class of issues in Requests that have had negative impact across a number
  of use cases. The Requests team has decided to revert this feature as long term
  maintenance of it is proving to be unsustainable in its current iteration.

Deprecations

• Added support for Python 3.14.
• Dropped support for Python 3.8 following its end of support.

v2.32.4

Compare Source

Security

• CVE-2024-47081 Fixed an issue where a maliciously crafted URL and trusted
  environment will retrieve credentials for the wrong hostname/machine from a
  netrc file.

Improvements

• Numerous documentation improvements

Deprecations

• Added support for pypy 3.11 for Linux and macOS.
• Dropped support for pypy 3.9 following its end of support.

v2.32.3

Compare Source

Bugfixes

• Fixed bug breaking the ability to specify custom SSLContexts in sub-classes of
  HTTPAdapter. (#​6716)
• Fixed issue where Requests started failing to run on Python versions compiled
  without the ssl module. (#​6724)

v2.32.2

Compare Source

Deprecations

• To provide a more stable migration for custom HTTPAdapters impacted
  by the CVE changes in 2.32.0, we've renamed _get_connection to
  a new public API, get_connection_with_tls_context. Existing custom
  HTTPAdapters will need to migrate their code to use this new API.
  get_connection is considered deprecated in all versions of Requests>=2.32.0.

  A minimal (2-line) example has been provided in the linked PR to ease
  migration, but we strongly urge users to evaluate if their custom adapter
  is subject to the same issue described in CVE-2024-35195. (#​6710)

v2.32.1

Compare Source

Bugfixes

• Add missing test certs to the sdist distributed on PyPI.

v2.32.0

Compare Source

Security

• Fixed an issue where setting verify=False on the first request from a
  Session will cause subsequent requests to the same origin to also ignore
  cert verification, regardless of the value of verify.
  (GHSA-9wx4-h78v-vm56)

Improvements

• verify=True now reuses a global SSLContext which should improve
  request time variance between first and subsequent requests. It should
  also minimize certificate load time on Windows systems when using a Python
  version built with OpenSSL 3.x. (#​6667)
• Requests now supports optional use of character detection
  (chardet or charset_normalizer) when repackaged or vendored.
  This enables pip and other projects to minimize their vendoring
  surface area. The Response.text() and apparent_encoding APIs
  will default to utf-8 if neither library is present. (#​6702)

Bugfixes

• Fixed bug in length detection where emoji length was incorrectly
  calculated in the request content-length. (#​6589)
• Fixed deserialization bug in JSONDecodeError. (#​6629)
• Fixed bug where an extra leading / (path separator) could lead
  urllib3 to unnecessarily reparse the request URI. (#​6644)

Deprecations

• Requests has officially added support for CPython 3.12 (#​6503)
• Requests has officially added support for PyPy 3.9 and 3.10 (#​6641)
• Requests has officially dropped support for CPython 3.7 (#​6642)
• Requests has officially dropped support for PyPy 3.7 and 3.8 (#​6641)

Documentation

• Various typo fixes and doc improvements.

Packaging

• Requests has started adopting some modern packaging practices.
  The source files for the projects (formerly requests) is now located
  in src/requests in the Requests sdist. (#​6506)
• Starting in Requests 2.33.0, Requests will migrate to a PEP 517 build system
  using hatchling. This should not impact the average user, but extremely old
  versions of packaging utilities may have issues with the new packaging format.

v2.31.0

Compare Source

Security

• Versions of Requests between v2.3.0 and v2.30.0 are vulnerable to potential
  forwarding of Proxy-Authorization headers to destination servers when
  following HTTPS redirects.

  When proxies are defined with user info (https://user:pass@proxy:8080), Requests
  will construct a Proxy-Authorization header that is attached to the request to
  authenticate with the proxy.

  In cases where Requests receives a redirect response, it previously reattached
  the Proxy-Authorization header incorrectly, resulting in the value being
  sent through the tunneled connection to the destination server. Users who rely on
  defining their proxy credentials in the URL are strongly encouraged to upgrade
  to Requests 2.31.0+ to prevent unintentional leakage and rotate their proxy
  credentials once the change has been fully deployed.

  Users who do not use a proxy or do not supply their proxy credentials through
  the user information portion of their proxy URL are not subject to this
  vulnerability.

  Full details can be read in our Github Security Advisory
  and CVE-2023-32681.
