2.6.3

🚀 urllib3 is fundraising for HTTP/2 support

urllib3 is raising ~$40,000 USD to release HTTP/2 support and ensure long-term sustainable maintenance of the project after a sharp decline in financial support. If your company or organization uses Python and would benefit from HTTP/2 support in Requests, pip, cloud SDKs, and thousands of other projects please consider contributing financially to ensure HTTP/2 support is developed sustainably and maintained for the long-haul.

Thank you for your support.

Thank you for your support.

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. (CVE-2025-66471 reported by @​Cycloctane, 8.9 High, 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. (CVE-2025-66418 reported by @​illia-v, 8.9 High, GHSA-gm62-xv2j-4w53)

[!IMPORTANT]

  • 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.

  • Fix AttributeError when initializing DebuggedApplication with pin_security=False. #3075

3.1.4

This is the Werkzeug 3.1.4 fix release, which fixes bugs but does not otherwise change behavior and should not result in breaking changes compared to the latest feature release.

  • Initial data passed to MultiDict and similar interfaces only accepts list, tuple, or set when passing multiple values. It had been changed to accept any Collection, but this matched types that should be treated as single values, such as bytes. #2994
  • When the Host header is not set and Request.host falls back to the WSGI SERVER_NAME value, if that value is an IPv6 address it is wrapped in [] to match the Host header. #2993

3.1.2

This is the Werkzeug 3.1.2 fix release, which fixes bugs but does not otherwise change behavior and should not result in breaking changes vs 3.1.0.

  • 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.

2.6.3 (2026-01-07)

  • 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) <https://github.com/urllib3/urllib3/issues/3743>__)
  • Fixed urllib3.connection.VerifiedHTTPSConnection on Emscripten. ([#3752](https://github.com/urllib3/urllib3/issues/3752) <https://github.com/urllib3/urllib3/issues/3752>__)

2.6.2 (2025-12-11)

  • 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) <https://github.com/urllib3/urllib3/issues/3734>__)

2.6.1 (2025-12-08)

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

2.6.0 (2025-12-05)

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>__)

Updates pip from 24.0 to 26.0

Changelog

Sourced from pip's changelog.

26.0 (2026-01-30)

Deprecations and Removals

  • Remove support for non-bare project names in egg fragments. Affected users should use the Direct URL requirement syntax <https://packaging.python.org/en/latest/specifications/version-specifiers/#direct-references>. ([#13157](https://github.com/pypa/pip/issues/13157) <https://github.com/pypa/pip/issues/13157>)

Features

  • Display pip's command-line help in colour, if possible. ([#12134](https://github.com/pypa/pip/issues/12134) <https://github.com/pypa/pip/issues/12134>_)

  • Support installing dependencies declared with inline script metadata (:pep:723) with --requirements-from-script. ([#12891](https://github.com/pypa/pip/issues/12891) <https://github.com/pypa/pip/issues/12891>_)

  • Add --all-releases and --only-final options to control pre-release and final release selection during package installation. ([#13221](https://github.com/pypa/pip/issues/13221) <https://github.com/pypa/pip/issues/13221>_)

  • Add --uploaded-prior-to option to only consider packages uploaded prior to a given datetime when the upload-time field is available from a remote index. ([#13625](https://github.com/pypa/pip/issues/13625) <https://github.com/pypa/pip/issues/13625>_)

  • Add --use-feature inprocess-build-deps to request that build dependencies are installed within the same pip install process. This new mechanism is faster, supports --no-clean and --no-cache-dir reliably, and supports prompting for authentication.

    Enabling this feature will also enable --use-feature build-constraints. This feature will become the default in a future pip version. ([#9081](https://github.com/pypa/pip/issues/9081) <https://github.com/pypa/pip/issues/9081>_)

  • pip cache purge and pip cache remove now clean up empty directories and legacy files left by older pip versions. ([#9058](https://github.com/pypa/pip/issues/9058) <https://github.com/pypa/pip/issues/9058>_)

Bug Fixes

  • Fix selecting pre-release versions when only pre-releases match. For example, package>1.0 with versions 1.0, 2.0rc1 now installs 2.0rc1 instead of failing. ([#13746](https://github.com/pypa/pip/issues/13746) <https://github.com/pypa/pip/issues/13746>_)
  • Revisions in version control URLs now must be percent-encoded. For example, use git+https://example.com/repo.git@issue%231 to specify the branch issue#1. If you previously used a branch name containing a % character in a version control URL, you now need to replace it with %25 to ensure correct percent-encoding. ([#13407](https://github.com/pypa/pip/issues/13407) <https://github.com/pypa/pip/issues/13407>_)
  • Preserve original casing when a path is displayed. ([#6823](https://github.com/pypa/pip/issues/6823) <https://github.com/pypa/pip/issues/6823>_)
  • Fix bash completion when the $IFS variable has been modified from its default. ([#13555](https://github.com/pypa/pip/issues/13555) <https://github.com/pypa/pip/issues/13555>_)
  • Precompute Python requirements on each candidate, reducing time of long resolutions. ([#13656](https://github.com/pypa/pip/issues/13656) <https://github.com/pypa/pip/issues/13656>_)
  • Skip redundant work converting version objects to strings when using the importlib.metadata backend. ([#13660](https://github.com/pypa/pip/issues/13660) <https://github.com/pypa/pip/issues/13660>_)
  • Fix pip index versions to honor only-binary/no-binary options. ([#13682](https://github.com/pypa/pip/issues/13682) <https://github.com/pypa/pip/issues/13682>_)
  • Fix fallthrough logic for options, allowing overriding global options with defaults from user config. ([#13703](https://github.com/pypa/pip/issues/13703) <https://github.com/pypa/pip/issues/13703>_)
  • Use a path-segment prefix comparison, not char-by-char. ([#13777](https://github.com/pypa/pip/issues/13777) <https://github.com/pypa/pip/issues/13777>_)
