chore(deps): bump urllib3 from 2.5.0 to 2.6.0

[dependabot]

Bumps urllib3 from 2.5.0 to 2.6.0.

Release notes

Sourced from urllib3's releases.

2.6.0

🚀 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.

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.
• If you use custom decompressors, please make sure to update them to respect the changed API of urllib3.response.ContentDecoder.

Features

• Enabled retrieval, deletion, and membership testing in HTTPHeaderDict using bytes keys. (#3653)
• Added host and port information to string representations of HTTPConnection. (#3666)
• Added support for Python 3.14 free-threading builds explicitly. (#3696)

Removals

• Removed the HTTPResponse.getheaders() method in favor of HTTPResponse.headers. Removed the HTTPResponse.getheader(name, default) method in favor of HTTPResponse.headers.get(name, default). (#3622)

Bugfixes

• Fixed redirect handling in urllib3.PoolManager when an integer is passed for the retries parameter. (#3649)
• Fixed HTTPConnectionPool when used in Emscripten with no explicit port. (#3664)
• Fixed handling of SSLKEYLOGFILE with expandable variables. (#3700)

Misc

• Changed the zstd extra to install backports.zstd instead of zstandard on Python 3.13 and before. (#3693)
• Improved the performance of content decoding by optimizing BytesQueueBuffer class. (#3710)
• Allowed building the urllib3 package with newer setuptools-scm v9.x. (#3652)
• Ensured successful urllib3 builds by setting Hatchling requirement to ≥ 1.27.0. (#3638)
