Release Notes

urllib3/urllib3 (urllib3)

`v2.7.0`

Compare Source

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

Security

Addressed high-severity security issues.
Impact was limited to specific use cases detailed in the accompanying
advisories; overall user exposure was estimated to be marginal.

Decompression-bomb safeguards of the streaming API were bypassed:
1. When HTTPResponse.drain_conn() was called after the response had been
  read and decompressed partially.
2. During the second HTTPResponse.read(amt=N) or
  HTTPResponse.stream(amt=N) call when the response was decompressed
  using the official Brotli <https://pypi.org/project/brotli/>__ library.
See GHSA-mf9v-mfxr-j63j <https://github.com/urllib3/urllib3/security/advisories/GHSA-mf9v-mfxr-j63j>__
for details.
HTTP pools created using ProxyManager.connection_from_url did not strip
sensitive headers specified in Retry.remove_headers_on_redirect when
redirecting to a different host.
(GHSA-qccp-gfcp-xxvc <https://github.com/urllib3/urllib3/security/advisories/GHSA-qccp-gfcp-xxvc>__)

Deprecations and Removals

Used FutureWarning instead of DeprecationWarning for better
visibility of existing deprecation notices. Rescheduled the removal of
deprecated features to version 3.0.
(#3763 <https://github.com/urllib3/urllib3/issues/3763>__)
Removed support for end-of-life Python 3.9.
(#3720 <https://github.com/urllib3/urllib3/issues/3720>__)
Removed support for end-of-life PyPy3.10.
(#4979 <https://github.com/urllib3/urllib3/issues/4979>__)
Bumped the minimum supported pyOpenSSL version to 19.0.0.
(#3777 <https://github.com/urllib3/urllib3/issues/3777>__)

Bugfixes

Fixed a bug where HTTPResponse.read(amt=None) was ignoring decompressed
data buffered from previous partial reads.
(#3636 <https://github.com/urllib3/urllib3/issues/3636>__)
Fixed a bug where HTTPResponse.read() could cache only part of the
response after a partial read when cache_content=True.
(#4967 <https://github.com/urllib3/urllib3/issues/4967>__)
Fixed HTTPResponse.stream() and HTTPResponse.read_chunked() to handle
amt=0.
(#3793 <https://github.com/urllib3/urllib3/issues/3793>__)
Updated _TYPE_BODY type alias to include missing Iterable[str],
matching the documented and runtime behavior of chunked request bodies.
(#3798 <https://github.com/urllib3/urllib3/issues/3798>__)
Fixed LocationParseError when paths resembling schemeless URIs were
passed to HTTPConnectionPool.urlopen().
(#3352 <https://github.com/urllib3/urllib3/issues/3352>__)
Fixed BaseHTTPResponse.readinto() type annotation to accept
memoryview in addition to bytearray, matching the
io.RawIOBase.readinto contract and enabling use with
io.BufferedReader without type errors.
(#3764 <https://github.com/urllib3/urllib3/issues/3764>__)

`v2.6.3`

Compare Source

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

Fixed a high-severity security issue where decompression-bomb safeguards of
the streaming API were bypassed when HTTP redirects were followed.
(GHSA-38jv-5279-wg99 <https://github.com/urllib3/urllib3/security/advisories/GHSA-38jv-5279-wg99>__)
Started treating Retry-After times greater than 6 hours as 6 hours by
default. (#3743 <https://github.com/urllib3/urllib3/issues/3743>__)
Fixed urllib3.connection.VerifiedHTTPSConnection on Emscripten.
(#3752 <https://github.com/urllib3/urllib3/issues/3752>__)

`v2.6.2`

Compare Source

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

Fixed HTTPResponse.read_chunked() to properly handle leftover data in
the decoder's buffer when reading compressed chunked responses.
(#3734 <https://github.com/urllib3/urllib3/issues/3734>__)

`v2.6.1`

Compare Source

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

Restore previously removed HTTPResponse.getheaders() and
HTTPResponse.getheader() methods.
(#3731 <https://github.com/urllib3/urllib3/issues/3731>__)

`v2.6.0`

Compare Source

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

Security

Fixed a security issue where streaming API could improperly handle highly
compressed HTTP content ("decompression bombs") leading to excessive resource
consumption even when a small amount of data was requested. Reading small
chunks of compressed data is safer and much more efficient now.
(GHSA-2xpw-w6gg-jr37 <https://github.com/urllib3/urllib3/security/advisories/GHSA-2xpw-w6gg-jr37>__)
Fixed a security issue where an attacker could compose an HTTP response with
virtually unlimited links in the Content-Encoding header, potentially
leading to a denial of service (DoS) attack by exhausting system resources
during decoding. The number of allowed chained encodings is now limited to 5.
(GHSA-gm62-xv2j-4w53 <https://github.com/urllib3/urllib3/security/advisories/GHSA-gm62-xv2j-4w53>__)

.. caution::

If urllib3 is not installed with the optional urllib3[brotli] extra, but
your environment contains a Brotli/brotlicffi/brotlipy package anyway, make
sure to upgrade it to at least Brotli 1.2.0 or brotlicffi 1.2.0.0 to
benefit from the security fixes and avoid warnings. Prefer using
urllib3[brotli] to install a compatible Brotli package automatically.
If you use custom decompressors, please make sure to update them to
respect the changed API of urllib3.response.ContentDecoder.
