When making requests through a Requests Session, if the first request is made with verify=False to disable cert verification, all subsequent requests to the same origin will continue to ignore cert verification regardless of changes to the value of verify. This behavior will continue for the lifecycle of the connection in the connection pool.
Remediation
Any of these options can be used to remediate the current issue, we highly recommend upgrading as the preferred mitigation.
Upgrade to requests>=2.32.0.
For requests<2.32.0, avoid setting verify=False for the first request to a host while using a Requests Session.
For requests<2.32.0, call close() on Session objects to clear existing connections if verify=False is used.

### [`v2.32.3`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2323-2024-05-29)
[Compare Source](https://togithub.com/psf/requests/compare/v2.32.2...v2.32.3)
**Bugfixes**
- Fixed bug breaking the ability to specify custom SSLContexts in sub-classes of
HTTPAdapter. ([#6716](https://togithub.com/psf/requests/issues/6716))
- Fixed issue where Requests started failing to run on Python versions compiled
without the `ssl` module. ([#6724](https://togithub.com/psf/requests/issues/6724))
### [`v2.32.2`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2322-2024-05-21)
[Compare Source](https://togithub.com/psf/requests/compare/v2.32.1...v2.32.2)
**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](https://togithub.com/psf/requests/issues/6710))
### [`v2.32.1`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2321-2024-05-20)
[Compare Source](https://togithub.com/psf/requests/compare/v2.32.0...v2.32.1)
**Bugfixes**
- Add missing test certs to the sdist distributed on PyPI.
### [`v2.32.0`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2320-2024-05-20)
[Compare Source](https://togithub.com/psf/requests/compare/v2.31.0...v2.32.0)
**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`.
(https://github.com/psf/requests/security/advisories/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](https://togithub.com/psf/requests/issues/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](https://togithub.com/psf/requests/issues/6702))
**Bugfixes**
- Fixed bug in length detection where emoji length was incorrectly
calculated in the request content-length. ([#6589](https://togithub.com/psf/requests/issues/6589))
- Fixed deserialization bug in JSONDecodeError. ([#6629](https://togithub.com/psf/requests/issues/6629))
- Fixed bug where an extra leading `/` (path separator) could lead
urllib3 to unnecessarily reparse the request URI. ([#6644](https://togithub.com/psf/requests/issues/6644))
**Deprecations**
- Requests has officially added support for CPython 3.12 ([#6503](https://togithub.com/psf/requests/issues/6503))
- Requests has officially added support for PyPy 3.9 and 3.10 ([#6641](https://togithub.com/psf/requests/issues/6641))
- Requests has officially dropped support for CPython 3.7 ([#6642](https://togithub.com/psf/requests/issues/6642))
- Requests has officially dropped support for PyPy 3.7 and 3.8 ([#6641](https://togithub.com/psf/requests/issues/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](https://togithub.com/psf/requests/issues/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`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2310-2023-05-22)
[Compare Source](https://togithub.com/psf/requests/compare/v2.30.0...v2.31.0)
**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.

**Dependencies**
- ⚠️ Added support for urllib3 2.0. ⚠️
This may contain minor breaking changes so we advise careful testing and
reviewing https://urllib3.readthedocs.io/en/latest/v2-migration-guide.html
prior to upgrading.
Users who wish to stay on urllib3 1.x can pin to `urllib3<2`.
### [`v2.29.0`](https://togithub.com/psf/requests/blob/HEAD/HISTORY.md#2290-2023-04-26)
[Compare Source](https://togithub.com/psf/requests/compare/v2.28.2...v2.29.0)
**Improvements**
- Requests now defers chunked requests to the urllib3 implementation to improve
standardization. ([#6226](https://togithub.com/psf/requests/issues/6226))
- Requests relaxes header component requirements to support bytes/str subclasses. ([#6356](https://togithub.com/psf/requests/issues/6356))
